Special Function Registers
All registers, except the program counter and the four general purpose register banks, reside in the
special function register area.
The 36 special function register (SFR) include pointers and registers that provide an interface
between the CPU and the other on-chip peripherals. There are also 128 directly addressable bits
within the SFR area.
All SFRs are listed in
table 1
,
table 2
and
table 3
. In
table 1
they are organized in numeric order
of their addresses. In
table 2
they are organized in groups which refer to the functional blocks of the
SAB-C502.
Table 3
illustrates the contents of the SFRs.
