[Fx2lib-devel] Interrupting on GPIF idle

[Eric W. <er...@wi...>]

In the Cypress frameworks code (pariph.c) there are two interrupt functions:

void ISR_GpifComplete(void) interrupt 0
{
}
void ISR_GpifWaveform(void) interrupt 0
{
}

 From my study yesterday I believe that I can have ISR_GpifComplete() 
execute when a GPIF transaction goes idle.  I would like to use this to 
count GPIF transactions and insert a USB packet containing this count 
and a marker between GPIF transactions.  To date I have been starting 
the GPIF only with GpifInit() at the start of my firmware.  Is there 
another way to restart the GPIF after it goes idle without calling 
GpifInit() again?
