3.3 Special Function Registers

All registers, except the program counter and the four general purpose register banks, reside in the

special function register area. The 81 special function registers include arithmetic registers,

pointers, and registers that provide an interface between the CPU and the on-chip peripherals.

There are also 128 directly addressable bits within the SFR area. All special function registers are

listed in table 3-1 and table 3-2.

In table 3-1 they are organized in numeric order of their addresses. In table 3-2 they are organized

in groups which refer to the functional blocks of the SAB 80C517A.
