GPC71XXXA

7 FUNCTION DESCRIPTIONS

7.1 CPU

7.6 SPU

One channel SPU supports MIDI playback with A3400Pro-like

decode or PCM format, and each channel has an 8-bit envelope

control.

GPC71XXXA features a 4-bit RISC CPU, executing the 12-bit

instruction set with total of 72 instructions available, 7 stacks

managed by a 3-bit stack pointer, three DPRs(Data Pointer to

read ROM) sharing stack 4 ~ 6, and two VPRs(Voice Data Pointer)

for SPU.

7.7 PWM

The PWM module consists of a 14-bit PWM driver to drive

speaker directly.

7.2 Memory

7.2.1 SRAM

7.8 Sleep Mode, Wakeup and Watchdog

7.8.1 Sleep mode and wakeup

There are 256 nibbles of SRAM, grouped into 4 banks. Each

bank has 64 nibbles and supports index mode to read/write its

content addressed by TXR.

Sleep mode or known as power down mode is an operating state

that requires an extremely low power consumption to maintain the

system in active. The sleep mode is particularly useful for the

application areas where the system is required to constantly

maintain its basic functionality and where the power capacity is

7.2.2 OTP

GPC71XXXA is equipped with 680K/ 340K/ 160K/ 128K/ 96K/

64K/ 32K x 12-bit factory programmed OTP memory.

limited.

GPC71XXXA enters sleep mode when SLEEP

instruction is executed and can be woken up by interrupt or key

state change. CPU will continue to execute the rest of program

code from where it entered sleep mode.

7.3 Clock Source

Clock source is an inner resistance oscillator with CPU clock

options of 1MHz or 2MHz

7.8.2 Watchdog Reset

7.4 Low Voltage Reset

A watchdog reset is a reset signal that is generated to reset the

entire system when watchdog counter is overflow. In case when

the program code has been running into an unknown state and

without the watchdog signal being cleared for a certain period of

time, watchdog function automatically generates a reset signal

pulling the system back from unknown state.

With the LVR function, a reset signal is generated to reset system

when the operating voltage drops below LVR level.

7.5 Interrupt

An interrupt is a special event request to microcontroller. When

it occurs, the corresponding interrupt will activate and direct the

program code to execute the respective functions.

The

7.9 I/O

GPC71XXXA has interrupt sources. Please refer to

The GPC71XXXA features 16-bit or 8-bit programmable

Input/output pins and many of them feature wakeup capability.

These IOs normally support input function with floating or pull-low

and output options. In addition to the ordinary I/O function, some

IO ports have special functions. The following table summarizes

the special functions for these IOs.

programming guide for more details.

7.5.1 Timebase

There are two Timebases, TB1 and TB2, generated by the system

clock. The interval of TB1 is allowed up to 1ms and TB2 allows

up to 2ms.
