NOTES:

1. Location of the exception vector table is determined by the vector base register. The vector address is the sum of the vector

base register and the vector offset.

2. 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.

3. Unused addresses within the internal register block are mapped externally. "RESERVED" blocks are not mapped externally.

4. Some internal registers are not available in user space.
