Current Status of the READYx Pins for the CY7C68013

Question: Is it possible to read the current pin status of the GPIF ready lines through firmware?

 

Answer:

As mentioned in section 15.13.15 of the EZ-USB technical reference manual, the current state of the RDY[5:0] pins can be read from the GPIFREADYSTAT register.  This register contains the state of the READY[5:0] lines sampled at each rising edge of the GPIF clock.
