SOFTWARE APPLICATIONS
This chapter provides explanations of how to use the W56000, W56xxx and instruction set
features along with assembly language coding examples. Besides, some demo programs are
also provided to demonstrate the functions. Users can get the object files from the example
program directory and download directly to ICE system to run the programs.
Trigger Debounce
Since all P0 and P1 triggers ( total 8 pins ) share the same TG interrupt vector, users have to
further differentiate the real one source from others by programming. Also, trigger debounce
should be considered in the TG section.
The following two assembly source code provide explanations of how to do these works by
software instruction.
Example 0
-1 : Use only P0 as input pins. (For your reference only)
