SPECIAL FUNCTION REGISTERS
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control the
operation of the device (Table 4-1).
The Special Function Registers can be classified into
two sets. The Special Function Registers associated
with the “core” functions are described in this section.
Those related to the operation of the peripheral
features are described in the section for each
peripheral feature.

Legend:
— = unimplemented, read as ‘0’, x = unknown, u = unchanged, q = value depends on condition.
Note
1:
The upper byte of the Program Counter is not directly accessible. See Section 4.7 “Program Counter” for an
explanation of how to access these bits.
2:
Other (non Power-up) Resets include external Reset through MCLR, Watchdog Timer and wake-up on pin change
Reset.
3:
See Table 9-1 for other Reset specific values.
4:
PIC10F204/206 only.
5:
PIC10F204/206 only. On all other devices, this bit is reserved and should not be used.
