5. FUNCTIONAL DESCRIPTION

I/O pins:

The W523Axxx family provides up to 4 trigger pins, which can be extended to 24 matrix trigger inputs,

up to 5 STOP output pins and up to 2 LED output pins. All of these I/O pins’ status can be easily

defined by

PowerSpeech



program.

Powerful programmable features:

The W523Axxx family provides JUMP (JP), LOAD (LD), MOVE (MV), INC, and END commands and

10 programmable registers, such as R0 ~ R3, EN0, EN1, MODE0, MODE1, STOP and PAGE, can be

easily used to program the desired playing mode, stop output signal form, LED flash type, and trigger

pin interrupt modes. The chip’s programmable features can also be used to develop new, customized

functions for a wide variety of innovative applications.

Programmable Power-on Initialization:

Whenever the W523Axxx is powered on or pressed the

RESET

pin, the program contained in the

voice group will be executed after the power-on delay (about 160 mS), so the user can write a

program into this group to set the power-on initial state. If user does not wish to execute a program at

power-on, an “END” instruction should be entered in the group 32.

The interruption priority is shown as below while other trigger pins as well as JUMP (JP) command are

executing simultaneously during POI executing period:

POI > TG1F > TG1R > TG2F > TG2R > *TG5F > *TG5R > *TG6F > *TG6R > "JP" instruction.

*: TG3, TG4 for W523A008, W523A010

5.1

The register file in the W523Axxx family is composed of 10 registers, including 4 general-purpose

registers and 6 special purpose registers. They are defined to facilitate the operations for various

purposes. The default setting values of the registers are given in the following table.
