TMS320F28335: chip selects for xint zones

Part Number: TMS320F28335

hello,

for my tms320f28335 i put an external Fpga register memory mapped section to xint zone 0 and attached an external ram memory to xint zone 7. could you give me any hint on how to configure the two chip selects (xzcs0 and xzcs7) to work in the proper way when accessing the two zones?

thanks a lot

    Marcello,

    You can find the fixed address ranges that are mapped to XZCS0 and XZCS7 in the datasheet.

    XINTF will automatically assert the appropriate XZCSn signal based on the address that is accessed by the CPU or DMA.
