C511 / C513
Special Function Registers
All registers except the program counter and the four general purpose register banks reside in the
special function register area.
The 34 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 5 and table 6. In table 5 they are organized in groups which refer to the
functional blocks of the C511/C513. Table 6 illustrates the contents of the SFRs, e.g. the bits of the
SFRs, in numeric order of their addresses.
