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.
A. 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.
Instructions are programmed by writing LOAD and JUMP commands into the R0, EN, STOP, and
MODE registers.
