Note 1: Registers in BOLD will be present in every device.
2: These registers may not be implemented, or are implemented as other registers in
3: Not all locations may be implemented. Unimplemented locations will read as ’0’.
4: These locations are unimplemented in Bank1. Access to these unimplemented
some devices.
locations will access the corresponding Bank0 register.
