19.2.2 Applying Pin Stimulus

Once you have created/edited a pin stimulus file, you may apply the stimulus as

follows:

• Asynchronous stimulus (Type = Asynch): Press the Fire button. The designated

event occurs on the designated pin.

• Synchronous stimulus (Type = Synch): Check the enable field. A message is sent

to MPLAB SIM to update the stimuli. Thus whatever is displayed is current.

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