bytes are grouped into 4 banks of 8 registers, the next 16 bytes above the register banks form a block of bit addressable
memory space. The upper 128 bytes are not allocated for any special area or functions.
SFR M
The Special Function Register (SFR) space is used for port latches, counters/timers, peripheral control, data capture and
display. These registers can only be accessed by direct addressing. Sixteen of the addresses in the SFR space are both
bit and byte addressable. The bit addressable SFRs are those whose address ends in 0H or 8H. A summary of the SFR
map in address order is shown in Table 2.
