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. The special
function registers are listed in table 1. In this table they are organized in groups which refer to
the functional blocks of the SAB 80C517. Block names and symbols are listed in alphabetical
order.
