Special function registers (SFR)
A group of registers designated as special function register (SFR) is shown in
page
interfaces and I/O pins on the MCU module. The SFRs can be accessed only by using the
Direct Addressing method within the address range from 80h to FFh of internal 8032 SRAM.
Sixteen addresses in SFR address space are both byte- and bit-addressable. The bit-
addressable SFRs are noted in
106 of a possible 128 SFR addresses are occupied. The remaining unoccupied SFR
addresses (designated as “RESERVED” in
unoccupied locations will return an undefined value.
There is a separate set of control registers for the PSD module, designated as csiop, and
they are described in the
other functions on the PSD module are NOT controlled by SFRs.
SFRs are categorized as follows:
