TABLE 11-6: INITIALIZATION CONDITIONS FOR ALL REGISTERS (CONTINUED)

Power-on Reset,

Brown-out Reset

MCLR

Resets

WDT Reset

Wake-up via WDT or

Interrupt

Legend: u = unchanged, x = unknown, - = unimplemented bit, read as '0', q = value depends on condition,

r = reserved, maintain clear

Note 1: One or more bits in INTCON, PIR1 and/or PIR2 will be affected (to cause wake-up).

2: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector

(0004h).

3: See Table 11-5 for RESET value for specific condition.
