Special Function Registers
All registers, except the program counter and the four general purpose register banks, reside in the special
function register area.
The 27 special function registers (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 GMS90 series.
Table 3
illustrates the contents of the SFRs.
