Hello,
Please clarify the following doubts regarding GPMC communication with an external FPGA.
16 bit GPMC asynchronous mode is interfaced with FPGA using CS3 for normal data transfer & CS5 for DMA operation
1) If am transmitting 256kbytes over CS5 and at the same time I am operating CS3 for single write/read. How would be the behavior of GPMC. whether it will stop the DMA operation and start CS3 single write / read or immediately stop the DMA operation over CS5 ?
2) If am using 3 Chip selects. How would be the priority of data transfer operation over these chip selects ?
Waiting for your reply
thanks
