Input/output port pin (with interrupt-on-change).
Internal software programmable weak pull-up. In-circuit serial
programming clock.
Input/output port pin (with interrupt-on-change) or TMR0 clock input or
Interrupt 0 input. Internal software programmable weak pull-up.
Input/output (open drain) port pin (with interrupt-on-change) or Master
Clear External Reset input. Internal software programmable
weak pull-up.
Input/output port pin (with interrupt-on-change) or oscillator connection, or
CLKOUT output. Internal software programmable weak pull-up.
Input/output port pin (with interrupt-on-change) or clock input, or oscillator
connection. Internal software programmable weak pull-up.
Legend: TTL = TTL input, ST = Schmitt Trigger input
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
2: This buffer is a Schmitt Trigger input when used in Serial Programming mode.
