Special function registers
A map of the on-chip memory area called the Special Function Register (SFR) space is
shown in
In the SFRs not all of the addresses are occupied. Unoccupied addresses are not
implemented on the chip. READ accesses to these addresses will in general return random
data, and WRITE accesses will have no effect. User software should write '0s' to these
unimplemented locations.
