NOTES:
1. Location of the module control registers is determined by the state of the module mapping (MM) bit in the SIM configuration
register. Y = M111, where M is the state of the MM bit.
2. Unused addresses within the internal register block are mapped externally. "RESERVED" blocks are not mapped externally.
3. Some internal registers are not available in user space.
