19.3.1.3 CREATING/EDITING A REGISTER STIMULUS FILE (.RSTI)

A register stimulus file contains register stimulus information in hexadecimal,

return-delimited format. Any text editor or spreadsheet application may be used to

create or edit this file. The default extension is .rsti, but any extension may be used.

Assign a register stimulus file to a register in the Value column of a Synchronous

Stimulus file (*.ssti).

19.3.2 Applying File Stimulus

Once you have created/edited a file stimulus file, the stimulus is applied as the program

is run under MPLAB IDE. When the designated trigger is activated, the designated

event occurs.

Note: Do not choose a pin. It will not work with PC stimulus.

Note: You cannot inject file values into port registers, e.g., PORTB. Use pin

values. Also, you cannot inject file values into the W register.

Note: You may only have one register stimulus file assigned to one register at a

time.

Note: The Stimulus dialog must be open for stimulus to be active.
