Description
PORTB is a bi-directional I/O port. PORTB can be software pro-
grammed for internal weak pull-ups on all inputs.
PORTC is a bi-directional I/O port.
Read control for parallel slave port (See also WR and CS pins)
PORTD is a bi-directional I/O port.
PORTE is a bi-directional I/O port.
Interrupt on change pin.
Interrupt on change pin.
Interrupt on change pin. Serial programming clock. TTL input
buffer as general purpose I/O, Schmitt Trigger input buffer when
used as the serial programming clock.
Interrupt on change pin. Serial programming data. TTL input
buffer as general purpose I/O, Schmitt Trigger input buffer when
used as the serial programming data.
