Synopsis

The Simple FPGA design demonstrates how to implement host-accessible registers in an FPGA design. The registers can be accessed via the ADMXRC2_Read and ADMXRC2_Write API calls, or via a memory-mapped region. The latter method is demonstrated by the Simple sample application.

FPGA Space Usage

Nibble-reversed data register (REVDATA, local bus address 0x0)
Bits Mnemonic Type Function
31:0 VAL R/W When read, this register returns the nibble-reversed version of the last value written to it.

Nibble-reversed data register (DATA, local bus address 0x4)
Bits Mnemonic Type Function
31:0 VAL R/W When read, this register returns the last value written to it.
