DPRAM and SFR Areas
Note: High-byte accesses of SFRs using the 8-bit offset addressing mode are not
possible.
Note: Writing to any byte of an SFR causes the non-addressed complementary byte to
be cleared.
Note: GPRs can be accessed using the 8-bit offset addressing mode, but the GPRs are
not mapped into the SFR and ESFR memory area. Using the corresponding long
address instead of a GPR access executes an internal peripheral bus access.
The upper half of each register block is bit-addressable, so the respective control/status
bits can be modified directly, or checked using bit addressing.
