Memory Map and Registers
The memory map comprises of 32-bit aligned registers which can be accessed via 8-bit,
16-bit, or 32-bit accesses. Write access to reserved locations will generate a transfer error.
Read access to reserved locations will also generate a transfer error and the read data bus
will show all 0s. The Memory Map and complete module is in Big Endian format.
The module will not check for correctness of programmed values in the registers and
software must ensure that correct values are being written.
