Note:
During the BAT, activity on the ²clock² and
²data² line are ignored. The LED¢s are turned
on at the beginning and turned off at the end of
the BAT. The BAT takes a minimum of 450ms
after POR and a maximum of 2.5s. The re-
sponse to a satisfactory BAT completion is ²AA²
and response to BAT failure is an ²FC² error.
The reset keyboard command ²FF² will also
cause the keyboard to execute the BAT. Com-
pletion codes are sent between 300 and 500ms
after a reset command is acknowledged. After
the BAT, the keyboard sets the keys to
typematic and make/break, and sets the default
typematic rate and delay.
Reset
The commands may be sent to the HT82K628A at any
time and the HT82K628A will respond within 25ms ex-
cept when performing the internal diagnostics or execut-
ing a Reset command.
EDH - Set/Reset Status Indicators
Three status indicators on the keyboard-Num Lock,
Caps Lock, and Scroll Lock-are accessible by the host.
The HT82K628A activates or deactivates these indica-
tors when it receives a valid command-code sequence
from the system. The command sequence begins with
the command byte (hex ED). The HT82K628A responds
to the command byte with ACK, discontinues scanning,
assignments for this option byte are as follow:
Power-on
Two important activities take place when power is first
applied to the keyboard. The first is the presence of an
H/W signal POR (Power-On-Reset) that resets the key-
board processor. The second activity is the running of
the self test BAT (Basic Assurance Test) routine.

Command from the Host
If a bit for an indicator is set to 1, the indicator is turned
on. If a bit is set to 0, the indicator is turned off.
The following table shows the commands that the host
may send and their hexadecimal values.

HT82K628A
The HT82K628A responds to the option byte with ACK,
sets the indicators and if the HT82K628Awas previously
enabled, continues scanning. The status of the indica-
tors will reflect the bits in the option byte and can be acti-
vated or deactivated in any combination. If another
command is received in place of the option byte, execu-
tion of the Set/Reset Mode Indicators command is
stopped, with no change to the indicator status, and the
new command is processed.
scanning and waits for the system to issue the rate/de-
lay value byte. The HT82K628A responds to the value
byte with another ACK, sets the rate and delay to the
value indicated, and continues scanning (if it was previ-
ously enabled). Bit6 and 5 indicate the delay, and bits 4,
3, 2, 1 and 0 indicate the rate. Bit7 is always 0. The delay
is equal to 1 plus the binary value bit 6 and 5, multiplied
by 250ms±20%.
The period (interval from one typematic output to the
next) is determined by the following equation:
Immediately after power-on, the lights default to the off
state. If the Set Default and Default Disable commands
are received, the lamps remain in the state they were in
before the command was received.
Period = (8+A)*(2^B)*0.00417 seconds.
Where:
A = binary value of bits 2, 1, and 0.
B = binary value of bits 4, and 3.
EEH - Echo
Echo is a diagnostic aid. When the HT82K628A re-
ceives this command, it issues a hex EE response and if
the HT82K628A was previously enabled, continues
scanning.
The typematic rate is 1 for each period and are listed as
follows:

EFh and F1h are invalid commands and are not sup-
ported. If HT82K628A receives one of these and sends
it, the HT82K628A will not acknowledge the command,
but returns a Resend command and continues in its pre-
vious scanning state.
F0H - Select Alternate Scan Codes
This command instructs the HT82K628Ato select one of
the three sets of scan codes. The HT82K628A acknowl-
edges receipt of this command with ACK, clears both
the output buffer and the typematic key. The host then
sends the option byte and the keyboard responds with
another ACK. An option byte value of hex 01 selects
scan code set 1, hex 02 selects set 2 and hex 03 selects
code set3.
An option byte value of hex 00 causes the HT82K628A
to acknowledge with ACK and sends a byte telling the
host which scan code set is currently in use.
8.0
After establishing the new scan code set, the
HT82K628A returns to the scanning state it was in be-
fore receiving the Select Alternate Scan Codes com-
mand.

The default values for the HT82K628A are as follows:
Typematic rate= 10.9 characters per second ± 20%
Delay = 500ms±20%

The execution of this command stops without change to
the existing rate if another command is received instead

the HT82K628A. The HT82K628A responds with ACK,
discontinues scanning and sends the two keyboard ID
bytes hex 83h and Abh. After the output of the second ID
byte, the HT82K628A resumes scanning.
F4H - Enable
Upon receipt of this command, the HT82K628A will re-
spond with ACK, clears its output buffer, clears the last
typematic key, and starts scanning.
F3H - Set Typematic Rate/Delay
The host issues the Set Typematic Rate/Delay com-
mand to change the typematic rate and delay. The
HT82K628A responds to the command with ACK, stops

next data output. When a Resend is received, the
HT82K628A sends the previous output again (unless
the previous output was Resend, in which case the
HT82K628A sends the last byte before the Resend
command).
The Default Disable command resets all conditions to
the power on default states. The HT82K628A will re-
spond with ACK, clears its output buffer, sets the default
key types (scan code set 3 operation only) and
typematic rate/delay, and clears the last typematic key.
The HT82K628A then stops scanning and awaits further
command.

rate/delay, and clears the last typematic key then contin-
ues scanning.

00H or FFH - Key Detection Error
The HT82K628Asends a key detection error character if
conditions in the keyboard make it impossible to identify
a switch closure. If the HT82K628A is using scan code
set 1, the code is FFH. For sets 2 and 3, the code is 00H.
Set All Keys-Typematic/Make/Break
The HT82K628Awill respond with ACK, clears its output
buffer, sets all keys to the type indicated by this com-
mand, and continues scanning (if it was previously en-
abled). Although these commands can be sent using
any code set, they affect only scan code set 3 operation.
00H or FFH - Overrun
An overrun character is placed in the HT82K628A buffer
and replaces the last code when the buffer capacity has
been exceeded. The code is sent to the host when it
reaches the top of the buffer queue. If the HT82K628A is
using scan code set 1, the code is FFH. For sets 2 and 3,
the code is 00H.
FBH, FCH, FDH - Set Key Type
These commands instruct the HT82K628A to set indi-
vidual keys to the type listed below:

Command
Set Key Type-Typematic
Set Key Type-Make/Break

83AbH - Keyboard ID
FB

FD
The keyboard ID consists of 2 bytes, Hex 83AbH. The
HT82K628A responds to the Read ID with ACK, discon-
tinues scanning and sends 2 ID bytes. The low byte is
sent first followed by the high byte. Following the output
of Keyboard ID, the HT82K628A begins scanning.
The HT82K628Awill respond with ACK, clears its output
buffer and prepares to receive key identification. Key
identification is accomplished by the host identifying
each key by its scan code value as defined in scan code
set 3. Only scan code set 3 values are valid for key iden-
tification. The type of each identified key is set to the
value indicated by the command. Although these com-
mands can be sent using any code set, they affect only
scan code set 3 operation.
EEH - Echo
The HT82K628A sends this code in response to an
Echo command.
AAH - BAT Completion Code
Following satisfactory completion of the BAT, the
HT82K628A sends AAH. Any other code indicates key-
board failure.
FEH - Resend
The host sends this command when it detects an error in
any transmission from the HT82K628A. It is sent only af-
ter a data transmission and before the host allows the

Data input
FCH - BAT Failure Code
¨
¨
¨
¨
¨
The system overrides the clock line for at least
60ms.
If a BAT failure occurs, the HT82K628A sends this code,
discontinues scanning and waits for a host response or
reset.
The keyboard checks the clock line state at inter-
vals of 10ms
If a system request-to-send is detected, the key-
board counts 11 data bits.
FEH - Resend
The HT82K628A issues a Resend command following
receipt of an invalid input or any input with incorrect par-
ity. If the host sends nothing to the HT82K628A, no re-
sponse is required.
Data will be valid before the rising edge and beyond
the falling edge
After the 10th bit, the keyboard checks for an active
level on the ²data² line. If the line is active it is forced
to be inactive, and counts one more bit.
Data Communications
Note: This action signals the system that the
keyboard has received its data. Upon
reception of this signal, the system returns
to the ready state, in which it can accept
keyboard outputs or goes to the inhibit
state until it is ready.
·
Data output
¨
¨
If CLK=0, no transmission (keyboard is inhibited).
If CLK=1, DATA=0, no transmission (system re-
quest to send).
¨
¨
If CLK=1, DATA=1, transmission permitted.
Data will be valid before the trailing edge and be-
yond the leading edge of the clock.
If the keyboard ²data² line is found to be at an inactive
level following the 10th bit, a frame error has occurred,
and the keyboard continues to count until the ²data²
line becomes active. The keyboard then makes the
²data² line inactive and sends a Resend.
¨
¨
The KB checks the clock line for an active level of at
least every 60ms.
If line contention occurs (system brings the clock
low before the tenth clock), set clock=data=high.
