resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATtiny25/45/85 as listed in
“Alternate Functions of Port B” on page
On ATtiny25, the programmable I/O ports PB3 and PB4 (pins 2 and 3) are exchanged in
ATtiny15 Compatibility Mode for supporting the backward compatibility with ATtiny15.
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-

The reset pin can also be used as a (weak) I/O pin.
