Access Bank
When a = 0:
The BSR is ignored and the
Access Bank is used.
The first 96 bytes are general
purpose RAM (from Bank 0).
The remaining 160 bytes are
Special Function Registers
(from Bank 15).
When a = 1:
The BSR specifies the bank
used by the instruction.

Note 1: Addresses, F5Ah through F5Fh, are also used by SFRs, but are not part of the Access RAM. Users must always
use the complete address, or load the proper BSR value, to access these registers.
2: Addresses, F40h to F59h, are not implemented and are not accessible to the user.
