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 XXinstruction 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.
