SFR memory
The Special Function Register (SFR) space is used for port latches, timer, peripheral control, acquisition control and 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. Table
4 only presents the additional SFRs of the SAA56xx family over the SAA55xx family of devices. This
SFR map table must therefore be read in conjunction with the SAA55xx SFR map table.
A description of the new SFR bits is shown in Table
5, which presents the SFRs in alphabetical order.
