Hi,
Could you explain how to use DR_ADDR in GPIF master mode?
The address source could be address counter or register or threadsocket, how to set an address into the "register"? I can not find any related functions in the firmware API. For DR_DATA, we have CyU3PGpifWriteDataWords, do we have anything similiar to set the address?
Regards,
Limin

Dear JGR,
There is CY_U3P_PIB_GPIF_EGRESS_ADDRESS(thread_number) macro. It is located in gpif_regs.h (SDK 1.2.3). You shall assign it to some buffer (i.e uint32_t tmp_data[4]) and write there address value.
