Special Function Registers
The registers, except the program counter and the four general purpose register banks,
reside in the special function register area. The special function register area consists of
two portions: the standard special function register area and the mapped special function
register area. Two special function registers of the C515C (PCON1 and DIR5) are
located in the mapped special function register area. For accessing the mapped special
function register area, bit RMAP in special function register SYSCON must be set. All
other special function registers are located in the standard special function register area
which is accessed when RMAP is cleared (“0”). As long as bit RMAP is set, mapped
special function register area can be accessed. This bit is not cleared by hardware
automatically. Thus, when non-mapped/mapped registers are to be accessed, the bit
RMAP must be cleared/set by software, respectively each.

The 59 special function registers (SFRs) in the standard and mapped SFR area include
pointers and registers that provide an interface between the CPU and the other on-chip
are organized in groups which refer to the functional blocks of the C515C. The CAN-
numeric order of their addresses. Table 6 list the CAN-SFRs in numeric order of their
addresses.

RMAP = 1: The access to the mapped special function register
area is enabled.
