QUESTION

What does the wwatch built-in function in the µVision Debugger do?

ANSWER

The wwatch built-in function is prototyped as follows:

void wwatch (
  ulong address);

This built-in debugger function delays inside a signal function until the specified memory address is written to. 

This is useful when you create signal functions that simulate external hardware. You can pause signal function execution until your target program writes to a specific memory address.
