applications requiring very low standby current. Users can simply
enable the wakeup sources to stop CPU clock by writing the
STOP CLOCK Register. By doing that, CPU will enter standby
mode and the RAM and I/Os remain at their previous states until
being awakened. There are two types of wakeup sources in the
GPL812P02A, I/O PAD data transient (Port B/C/D Key change)
and 32K timer base wake up source(TBHF/TBLF). After the
GPL812P02A wakes up, CPU will go to the next state of where
CPU enters sleep mode. Wake-up action will not influence RAM
Register, Y Register, Stack pointer and Processor Status Register
(the same as the 6502 instruction structure).
5.2. Clock Source
The GPL812P02A equips two types of clock sources:
(1) High speed frequency to support the whole system operation.
There are two frequency options: 4MHz/8MHz and can be
selected by register based on various user’s application
needs. It comes from IOSC8M or XTAL8M.
and I/Os.
Note1: TBHF: 128Hz, 256Hz, 512Hz or 1KHz
Note2: TBLF: 2Hz, 4Hz, 8Hz or 16Hz
(2) Low speed frequency to control LCD frame rate and time
base timer. It is derived from IOSC32K or XTAL32K.
5.5. I/O Ports
5.3. ROM/RAM Area
The GPL812P02A has four IO ports: PortA, PortB, PortC and
PortD. These port pins may be multiplexed with an alternate
function for the peripheral features on the device. In general,
when an initial reset state occurs, all ports are used as a general
purpose input port. There are three parts in IO structure: data,
direction and attribution registers. Each corresponding bit in
these ports should be given a value.
The GPL812P02A features 16K-byte OTP-ROM that can be
defined as the program area, address located from $C000H to
$FFFFH. Its RAM consists of 256 bytes (including Stack) at
locations $80H~$FFH & $180H~$1FFH.

5.7. LCD Controller
5.9. OTP Programming Circuit
GPL812P02A contains a LCD controller/driver that provides the
capability to drive 4 commons and 32 segments LCD. To reduce
CPU overhead, a display buffer is designed for LCD mappings.
A
LCD dot/pattern is set ON or OFF by programming the
corresponding bit in the display buffer. In addition, the LCD can
be programmed as 1/2duty with 1/2bias, 1/3duty with 1/2bias,
1/3duty with 1/3bias or 1/4duty with 1/3bias. The VLCD level is
equal VDD. The LCD driver can also operate during sleep by
keeping 32K oscillator running.
5.8. Map of Memory
Note1: Don’t connect any component with PC3 and PC2 when
programming.
Note2: Connect VPP to Writer during OTP programming cycle, and keep it
floating in normal run.
