9 Do Not ConnectATtiny13A 2021 Microchip Technology Inc. data Sheet Complete DS40002307A-page 9 B (PB5:PB0)Port B is a 6-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). ThePort B output buffers have symmetrical drive characteristics with both high sink and sourcecapability. As inputs, Port B pins that are externally pulled low will source current if the pull-upresistors are activated. The Port B pins are tri-stated when a reset condition becomes active,even if the clock is not B also serves the functions of various special features of the ATtiny13A as listed on input. A low level on this pin for longer than the minimum pulse length will generate areset, even if the clock is not running and provided the reset pin has not been disabled.

10 The min-imum pulse length is given in Table 18-4 on page 126. Shorter pulses are not ensured togenerate a reset pin can also be used as a (weak) I/O 2021 Microchip Technology Inc. data Sheet Complete DS40002307A-page 10 2.
