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.

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.

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

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

vector (0004h).

See Table 12-5 for Reset value for specific condition.

If Reset was due to brown-out, then bit 0 = 0. All other Resets will cause bit 0 = u.

PIC16F616/16HV616 only.
