- = Unimplemented locations read as ‘0’, u = unchanged, x = unknown, q = value depends on condition, shaded = unimplemented

Other (non Power-up) Resets include MCLR Reset and Watchdog Timer Reset during normal operation.

PIC16F946 only, forced ‘0’ on PIC16F91X.

PIC16F914/917 and PIC16F946 only, forced ‘0’ on PIC16F913/916.

The value of the OSTS bit is dependent on the value of the Configuration Word (CONFIG) of the device. See Section 4.2 “Oscillator

Control”.

Bit is read-only; TRISE3 = 1 always.
