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 32nd
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
