Description

Legend:

I = input

O = output

I/O = input/output

P = power

— = Not used

TTL = TTL input

ST = Schmitt Trigger input

Note

1:

This buffer is a Schmitt Trigger input when configured as an external interrupt or LVP mode.

2:

This buffer is a Schmitt Trigger input when used in Serial Programming mode.

3:

This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel

Slave Port mode (for interfacing to a microprocessor bus).

4:

This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.
