3.23. Memory Mapped Register (MMR) Tables
The address buses to read and write from the MMR registers are 10 bits wide, while the read and write data buses are configured to be 32 bits. The Bits Register Link column in the table below provides the mapping on the width of the data read within the 32-bit bus. The reads and writes are always performed using the 32-bit-wide bus.
