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 second 160 bytes are
Special Function Registers
(from Bank 15).
When ‘a’ = 1:
The BSR specifies the Bank
used by the instruction.

SFR
Note 1: Addresses F38h 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.
