2.2.5 Register Map
Note:
All 32-bit registers are D-word aligned.
All 16-bit registers are also D-word aligned and right justified.
For the Little Endian CPUs, register offset bit [1,0] are always set to be 00.
For the Big Endian CPUs, register offset bit [1,0] are always set to be 10.
This is a Global Register. CPU is allowed to write the Global Register of all devices by a single operation.
These registers are reserved for system diagnostic usage only.
