Legend: u = unchanged, x = unknown, - = unimplemented bit, read as ‘0’, q = value depends on condition.
Note 1: Bits <7:2> of W register contain oscillator calibration values due to MOVLW XX instruction at top of memory.
Note 2: See Table 8-7 for RESET value for specific conditions
Note 3: If RESET was due to Wake-up-on-Pin Change, then bit 7 = 1. All other RESETS will cause bit 7 = 0.
