The Special Function Register (SFR) space is used for port latches, timer, peripheral control, acquisition control, display control, etc. 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.
A description of each of the SFR bits is shown in Table 3 which presents the SFRs in alphabetical order.
