Legend:

Note 1:

2:

3:

Shaded cells are not used by Port registers, read as ‘0’. – = unimplemented, read as ‘0’, x = unknown, u = unchanged,

q = depends on condition.

PIC12F508/509 only.

PIC16F505 only.

If Reset was due to wake-up on pin change, then bit 7 = 1. All other Resets will cause bit 7 = 0.
