C Bus
– On-chip Oscillator
– ADC
– I/O Ports
– USB
Special Function Registers
A map of the on-chip memory area called the Spe-
cial Function Register(SFR) spaceis shown in Ta-
ble 15.
Note:
In the SFRs not all of the addresses are oc-
cupied. Unoccupiedaddresses are not implement-
ed on the chip. READ accesses to these
addresses will in general return random data, and
WRITE accesses will have no effect. User soft-
ware should write ’0s’ to these unimplemented lo-
cations.
