DESCRIPTION
PIN CONFIGURATION
The Philips Semiconductors TPM749 is a small package, low cost,
ROM-coded 80C51 with IBM ’s TrackPoint pointing algorithms
and control code. TrackPoint is the result of years of human factors
research and innovation at IBM. The result is a “velocity sensitive”
pointing solution more efficient and easier to use than “position
sensitive” devices such as the mouse, the trackball, or the touchpad.

IBM has licensed Philips Semiconductors to sell microcontrollers
with TrackPoint code. By purchasing a TPM from Philips, the
purchaser becomes a sub-licensee of Philips. The selling price of
Philips’ TPM includes the royalties for IBM’s intellectual property,
which Philips in turn pays to IBM. Customers for TPMs do not need
to sign any licensing agreement with either IBM or Philips. This code
is the intellectual property of IBM, which is covered by numerous
patents, and must be treated accordingly.

1s written to them float, and in that state can be used as high-impedance inputs. P0.3–P0.4 are
bidirectional I/O port pins with internal pull-ups. These pins are driven low if the port register bit is
written with a 0. The state of the pin can always be read from the port register by the program. Port 0.3
and 0.4 have internal pull-ups that function identically to port 3. Pins that have 1s written to them are
pulled high by the internal pull-ups and can be used as inputs.
While P0.0 anbd P0.1 differ from “standard TTL” characteristics, they are close enough for the pins to
still be used as general-purpose I/O.

OSCILLATOR CHARACTERISTICS
X1 and X2 are the input and output, respectively, of an inverting
amplifier which can be configured for use as an on-chip oscillator.
I/O Ports
The I/O pins provided by the TPM consist of port 0, port 1, and
port 3.
To drive the device from an external clock source, X1 should be
driven while X2 is left unconnected. There are no requirements on
the duty cycle of the external clock signal, because the input to the
internal clock circuitry is through a divide-by-two flip-flop. However,
minimum and maximum high and low times specified in the data
sheet must be observed.
Port 0
Port 0 is a 5-bit bidirectional I/O port and includes alternate functions
on some pins of this port. Pins P0.3 and P0.4 are provided with
internal pullups while the remaining pins (P0.0, P0.1, and P0.2) have
open drain output structures. The alternate function for port P0.4 is
PWM output.
If the alternate function PWM is not being used, then this pin may be
used as an I/O port.
IDLE MODE
The TPM includes the 80C51 power-down and idle mode features.
In idle mode, the CPU puts itself to sleep while all of the on-chip
peripherals except the A/D and PWM stay active. The functions that
continue to run while in the idle mode are Timer 0, Timer I, and the
interrupts. The instruction to invoke the idle mode is the last
instruction executed in the normal operating mode before the idle
mode is activated. The CPU contents, the on-chip RAM, and all of
the special function registers remain intact during this mode. The
idle mode can be terminated either by any enabled interrupt (at
which time the process is picked up at the interrupt service routine
and continued), or by a hardware reset which starts the processor in
the same manner as a power-on reset. Upon powering-up the
circuit, or exiting from idle mode, sufficient time must be allowed for
stabilization of the internal analog reference voltages before an A/D
conversion is started.
Port 1
Port 1 is an 8-bit bidirectional I/O port whose structure is identical to
the 80C51, but also includes alternate input functions on all pins.
The alternate pin functions for port 1 are:
P1.0-P1.4 - ADC0-ADC4 - A/D converter analog inputs
P1.5 INT0 - external interrupt 0 input
P1.6 INT1 - external interrupt 1 input
P1.7 - T0 - timer 0 external input
If the alternate functions INT0, INT1, or T0 are not being used, these
pins may be used as standard I/O ports. It is necessary to connect
AV and AV to V and V , respectively, in order to use P1.5,
CC
SS
CC
SS
P1.6, and P1.7 pins as standard I/O pins. When the A/D converter is
enabled, the analog channel connected to the A/D may not be used
as a digital input; however, the remaining analog inputs may be used
as digital inputs. They may not be used as digital outputs. While the
A/D is enabled, the analog inputs are floating.
POWER-DOWN MODE
In the power-down mode, the oscillator is stopped and the
instruction to invoke power-down is the last instruction executed.
Only the contents of the on-chip RAM are preserved. A hardware
reset is the only way to terminate the power-down mode. The control
bits for the reduced power modes are in the special function register
PCON.
Port 3
Port 3 is an 8-bit bidirectional I/O port whose structure is identical to
the 80C51. Note that the alternate functions associated with port 3
of the 80C51 have been moved to port 1 of the TPM (as applicable).
See Figure 1 for port bit configurations.

NOTE:
Because the analog to digital converter has a sampled-data comparator, the input looks capacitive to a source. When a conversion
is initiated, switch Sm closes for 8tcy (8µs @ 12MHz crystal frequency) during which time capacitance Cs + Cc is charged. It should
be noted that the sampling causes the analog input to present a varying load to an analog source.

A/D CONVERTER PARAMETER DEFINITIONS
Gain Error
The following definitions are included to clarify some specifications
given and do not represent a complete set of A/D parameter
definitions.
Gain error is the deviation between the ideal and actual analog input
voltage required to cause the final code transition to a full-scale
output code after the offset error has been removed. This may
sometimes be referred to as full scale error.
Absolute Accuracy Error
Offset Error
Absolute accuracy error of a given output is the difference between
the theoretical analog input voltage to produce a given output and
the actual analog input voltage required to produce the same code.
Since the same output code is produced by a band of input voltages,
the “required input voltage” is defined as the midpoint of the band of
input voltage that will produce that code. Absolute accuracy error
not specified with a code is the maximum over all codes.
Offset error is the difference between the actual input voltage that
causes the first code transition and the ideal value to cause the first
code transition. This ideal value is 1/2 LSB above V
.
ref–
Channel to Channel Matching
Channel to channel matching is the maximum difference between
the corresponding code transitions of the actual characteristics
taken from different channels under the same temperature, voltage
and frequency conditions.
Nonlinearity
If a straight line is drawn between the end points of the actual
converter characteristics such that zero offset and full scale errors
are removed, then non-linearity is the maximum deviation of the
code transitions of the actual characteristics from that of the straight
line so constructed. This is also referred to as relative accuracy and
also integral non-linearity.
Crosstalk
Crosstalk is the measured level of a signal at the output of the
converter resulting from a signal applied to one deselected channel.
Total Error
Maximum deviation of any step point from a line connecting the ideal
first transition point to the ideal last transition point.
Differential Non-Linearity
Differential non-linearity is the maximum difference between the
actual and ideal code widths of the converter. The code widths are
the differences expressed in LSB between the code transition
points, as the input voltage is varied through the range for the
complete set of codes.
Relative Accuracy
Relative accuracy error is the deviation of the ADC’s actual code
transition points from the ideal code transition points on a straight
line which connects the ideal first code transition point and the final
code transition point, after nullifying offset error and gain error. It is
generally expressed in LSBs or in percent of FSR.
