Special Function Registers
A map of the on-chip memory area called the Special
Function Register (SFR) space is shown in the
Table1,
Table 2
and
Table 3
.
Note that not all of the addresses are occupied, and
unoccupied addresses may not be implemented on the
chip. Read accesses to these addresses will in general
return random data, and write accesses will have an
indeterminate effect.
User software should not write 1s to these unlisted
locations, since they may be used in future products to
invoke new features. In that case, the reset or inactive
values of the new bits will always be 0.
