Analog ground.
Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The Port A output buffers have symmetrical drive characteristics with both high sink and
source capability. As inputs, Port A pins that are externally pulled low will source current if the
pull-up resistors are activated. The Port A pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
Port A also serves the functions of various special features of the ATtiny87/167 as listed on
Section 9.3.3 “Alternate Functions of Port A” on page
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The Port B output buffers have symmetrical drive characteristics with both high sink and
source capability. As inputs, Port B pins that are externally pulled low will source current if the
pull-up 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 ATtiny87/167 as listed on
