14 / 46 page GMS90C320 10 OCT. 2000 Ver 1.2 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 GMS90C320. Table 3 illustrates the contents of the SFRs.
