I/O

CRYSTAL1: This is the crystal

oscillator input. This pin may be

driven by an external clock or

configurable I/O pin.

When

operating

as

I/O,

it

supports 4 output modes and

TTL/Schmitt trigger.

* TYPE: P: power, I: input, O: output, I/O: bi-directional, H: pull-high, L: pull-low, D: open-drain.

Table 5-1: Pin Description

Note:

On power-on-reset, all port pins will be tri-stated.

After power-on-reset, all port pins state will follow CONFIG0.PRHI bit definition.
