This is a 4-bit, bi-directional I/O port with internal pull-up resistors, individually selectable for
each bit. The output buffers have symmetrical drive characteristics, with both high sink and
source capability. As inputs, the port pins that are externally pulled low will source current if pull-
up resistors are activated. Port pins are tri-stated when a reset condition becomes active, even if
the clock is not running.
The port also serves the functions of various special features of the ATtiny4/5/9/10, as listed on
page
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 and provided the reset pin has not been disabled. The min-
imum pulse length is given in
generate a reset.
The reset pin can also be used as a (weak) I/O pin.
