$ADMXRC_SDK4/fpga/vhdl/simple
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.
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. |
