GPIF going "dry" waiting for data?

I am using the GPIF as a 32-bit Slave FIFO with 2-bit addressing.  I would like to know if there is a way to determine if the GPIF interface goes "dry" or empty while waiting for data from the GPIF master.

 Hi,

You can make use of DMA flags to check if the buffer is empty.Flags indicate empty or full, based on the direction of the 

socket.Please check the section on 'Configuration of Flags' in  AN65974-Designing with the EZ-USB FX3™ Slave FIFO Interface.

Regards,

Subha
