Special Function Registers
The registers, except the program counter and the four general purpose register banks, reside in
the special function register area.
The 43 special function registers (SFRs) include pointers and registers that provide an interface
between the CPU and the other on-chip peripherals. All SFRs with addresses where address bits
0-2 are 0 (e.g. 80 H , 88 H , 90 H , 98 H , ..., F8 H , FF H ) are bitaddressable.
The SFRs of the C515 are listed in table 3-1 and table 3-2. In table 3-1 they are organized in groups
which refer to the functional blocks of the C515. Table 3-2 illustrates the contents of the SFRs in
numeric order of their addresses.
