Supply voltage.
Ground.
Analog supply voltage.
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
Section 9.3.4 “Alternate Functions of Port B” on page

This documentation contains simple code examples that briefly show how to use various parts
of the device. These code examples assume that the part specific header file is included
before compilation. Be aware that not all C compiler vendors include bit definitions in the
header files and interrupt handling in C is compiler dependent. Please confirm with the C com-
piler documentation for more details.
