C504

Special Function Registers

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

special function register area.

The 63 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.

The SFRs of the C504 are listed in table 2 and table 3. In table 2 they are organized in groups

which refer to the functional blocks of the C504. Table 3 illustrates the contents of the SFRs in

numeric order of their addresses.
