6. FUNCTIONAL DESCRIPTION
The W528Sxx family provides up to four direct trigger pins, which can be extended to eight or twelve
matrix trigger inputs, up to three stop signal output pins, an LED section control, and powerful
programmable features. The JUMP and LOAD commands and four programmable registers can be
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.
6.1 Instruction Set Description
This section describes three types of instructions:
• Unconditional instructions, which are executed immediately after they are issued.
• Conditional instructions, which are executed only when the conditions specified in the instructions
are satisfied.
• END instruction, which is used to stop all device activity.

SOUND1 and SOUND2 are the *.WAM files of ADPCM converted voice data;
_FL is the section control setting, for which the parameters F and L are as follows:
F: Voice output frequency setting:
0 = 4 KHz, 1 = 4.8 KHz, 2 = 6 KHz, 3 = 8 KHz;
L: LED output setting:
1: ON
0: OFF; and
[1FFFF] is a period of silence of length 1FFFF;
H4, T4: Represent head and tail ADPCM files, respectively.
6.7 Programmable Power-on Initialization
Whenever the W528Sxx is powered on, 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 the user does not wish to execute a program at power-on, an "END"
instruction should be entered in group 32. The W528Sxx power-on initialization process can be
interrupted by trigger inputs.
6.8 Progamming Examples
This section presents several examples of how the functions of the W528Sxx may be programmed.
Customer programs should be written in ASCII code using a text editor; after compiling, the sound
effects resulting from the programs can be tested using a Winbond demo board.
EXAMPLE1: Four playing mode settings:
a. One-Shot Trigger Mode
0: LD EN, 0x01
; Enable TG1 falling edge input only.
H4 + sound1 + T4
