Legend: u= unchanged, x= unknown, – = unimplemented bit, reads as ‘0’, q= value depends on condition.  
Note 1: If VDD goes too low, Power-on Reset will be activated and registers will be affected differently.  
2: One or more bits in INTCON and/or PIR1 will be affected (to cause wake-up).  
3: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt  
vector (0004h).  
4: See Table 11-5 for Reset value for specific condition.  
5: If Reset was due to brown-out, then bit 0 = 0. All other Resets will cause bit 0 = u.

Interrupt Wake-up from Sleep  
Legend: u= unchanged, x= unknown, – = unimplemented bit, reads as ‘0’.  
Note 1: When the wake-up is due to an interrupt and Global Interrupt Enable bit, GIE, is set, the PC is loaded with  
the interrupt vector (0004h) after execution of PC + 1.
