– = 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.
The value of the OSTS bit is dependent on the value of the Configuration Word (CONFIG) of the device. See Section 4.0 “Clock
Sources”.
Bit is read-only; TRISE = 1 always.
PIC16F946 SPECIAL FUNCTION REGISTERS SUMMARY BANK 1
