µVISION DEBUGGER: Using the RWATCH Built-in Function

QUESTION

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

ANSWER

The rwatch built-in function is prototyped as follows:

void rwatch (
  ulong address);

This built-in debugger function delays inside a signal function until the specified memory address is read from. This is useful when you create signal functions that simulate external hardware. You can pause signal function execution until your target program reads from a specific memory address.
