This pin is used for GPIO. It is
individually programmed as input or
output and is also used individually as
an interrupt input. Each Port B pin,
when programmed as output is
selected to be an open-drain or open-
source output.
Input Capture A Signal to Timer 1.
This signal is multiplexed with PB0.
Event Counter Signal to Timer 1. This
signal is multiplexed with PB0.
