resistors are activated. The Port H pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port H also serves the functions of various special features of the ATmega640/1280/2560 as
listed on
Port J is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port J output buffers have symmetrical drive characteristics with both high sink and source capa-
bility. As inputs, Port J pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port J pins are tri-stated when a reset condition becomes active,
even if the clock is not running.

Port K serves as analog inputs to the A/D Converter.
Port K is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port K output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port K pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port K pins are tri-stated when a reset condition becomes active,
even if the clock is not running.

Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running. The minimum pulse length is given in
