FUNCTIONAL DESCRIPTION
I/O pins:
The W523Sxx 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 W523Sxx 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 W523Sxx is powered on or pressed the
RESET
pin, the program contained in the 32
nd
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
