TABLE 3-4: INITIALIZATION CONDITION FOR REGISTERS (CONTINUED)

Power-on Reset/

Brown-out Reset

(1)

MCLR Reset/

WDT Reset

Wake-up from Sleep through

Interrupt/Time-out

Legend: u = unchanged, x = unknown, - = unimplemented bit, reads as ‘0’, q = value depends on condition.

Note 1: If V

DD 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 and PIR2 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 3-5 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.

6: PIC16F724/727/PIC16LF724/727 only.
