GND
Ground.
1.1.3
Port B (PB3..PB0)
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 36.
1.1.4
RESET
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 minimum pulse length is given in Table 16-4
on page 118. Shorter pulses are not guaranteed to generate a reset.
The reset pin can also be used as a (weak) I/O pin.
