Hi
I use the EPI in GP mode for FPGA interface 16 bit.
The FPGA interface need 1 EPI clock cycle as bus turn-over from read to write cycle.
This mean that after read cycle , the system will insert one EPI clock as turn over and then the write cycle will perform.
My configuration:
// valu of 4 = clock of 20Mhz
EPIDividerSet(EPI0_BASE, 4);
EPIModeSet(EPI0_BASE, EPI_MODE_GENERAL);
EPIConfigGPModeSet(EPI0_BASE, EPI_FPGA_CONFIG, 8, 0);
EPIAddressMapSet(EPI0_BASE, EPI_ADDR_RAM_SIZE_64KB | EPI_ADDR_RAM_BASE_6);
thanks
