5. FUNCTIONAL DESCRIPTIONS
5.1. ROM Area
5.4. Time-Setting Register Related
GPL30A1 is a large ROM based micro-controller with 220 dots
LCD driver. The large ROM can be defined as a program ROM,
LCD font and audio data continuously without any limitation. To
access the ROM area, user should program the BANK SELECT
register ($07) first, then access the bank #1 or bank #2 by
addressing the higher bank address ($8000 - $FFFF) to fetch
data.
The basic time base of CPU wake-up and interrupt can be
changed by writing to TIME-SETTING register. For example, the
programmer can change 2Hz wake-up and interrupt into 1Hz
wake-up and interrupt by writing 80H into $0A. Therefore, this
system will wake-up to service every second. Also, T16Hz (one of
counter‘s clock source and wake-up & interrupt) can be one of
4Hz, 8Hz, 16Hz or 32Hz by setting bit0 and bit1 of
TIME-SETTING register ($0A). At power on state, T16Hz selects
4Hz, and T2Hz chooses 2Hz.
5.2. Stop Clock Mode
GPL30A1 supports power saving mode for those applications
requiring very low standby current. User can simply enable the
wake-up sources to stop the CPU clock by writing the STOP
CLOCK register ($09). Thus, CPU will enter standby mode and
the RAM and I/O retain in their previous state until awake. There
are four sources of wake-up in this chip: PORT IOEF wake-up,
TIMER 0 wake-up, 4Hz/8Hz/16Hz/32Hz wake-up and 2Hz/1Hz
wake-up. After the chip is awakened, the internal CPU will go to
the RESET state. The RAM and I/O are not affected by this
wake-up reset.
5.5. PWM Output
Internally, GPL30A1 has two sets of PWMs (one for each channel).
GPL30A1 uses Pulse Width Modulation that could directly drive
speaker or buzzer without any buffer or AMP circuit.
5.6. Speech and Melody
Since GPL30A1 carries a large ROM size and wide CPU
operating speed range, it is the most suitable device for speech
and melody application. For speech synthesis, this chip provides
INT for precise sampling frequency.
Users can record or
5.3. Map of Memory and I/Os
synthesize the sound and digitize it into ROM. The sound can be
played back in the sequence of the control functions as designed
by the internal user's program. Several algorithms are suggested
to be used for high fidelity and good compression of sound: PCM,

features dual tone mode. Once entered into the dual tone mode,
users only need to program the TM0 and TM1 to tone frequency
for each channel, count the envelope of each channel, and the
hardware can toggle the tone wave automatically without using
INT to handle it.

GPL30A1 contains a total of 220 segments LCD controller and
drivers. In the power-on state, LCD display is all on state. The
programmer can set the LCD status (bias, duty, normal scan) by
writing to LCD option ($1F), update the LCD content by writing to
LCD registers. After the power-on state, LCD option is defined
only one time and then fills the LCD registers to display the
desired pattern. The LCD driver is designed to fit most LCD's
specifications in GPL30A1. It can either be programmed as 1/2
or 1/3 bias. The duty is also programmable from 1/2, 1/3, 1/4 or

5.8. Timer/Counter
specified as a counter, user can reset the counter by loading 0 into
register $15 and $16 and loading 0 into the counter by writing to
$17. After the counter is activated, the count value can also be
read from above registers ($15 and $16) on-the-fly and the read
instruction will not affect the counter's value or reset it.
GPL30A1 features two 16-bit timer/counters, TM0 and TM1
respectively. In the timer mode, TM0 and TM1 are reloaded
up-counters. When timer overflows from $FFFF to $0000, the
carry signal will generate the INT signal if the corresponding bit is
enabled in INT ENABLE register ($0d), and the timer will auto
reload to the user setup value and up count again. If TM0 is
