Description
This pin can be used for general-purpose
I/O. It can be individually programmed as
input or output and can also be used
individually as an interrupt input. Each
Port B pin, when programmed as output,
can be selected to be an open-drain or
open-source output.
Alternate clock source for Programmable
Reload Timers 0 and 2. This signal is
multiplexed with PB0.
This pin can be used for general-purpose
I/O. It can be individually programmed as
input or output and can also be used
individually as an interrupt input. Each
Port B pin, when programmed as output,
can be selected to be an open-drain or
open-source output.
Alternate clock source for Programmable
Reload Timers 1 and 3. This signal is
multiplexed with PB1.
This pin can be used for general-purpose
I/O. It can be individually programmed as
input or output and can also be used
individually as an interrupt input. Each
Port B pin, when programmed as output,
can be selected to be an open-drain or
open-source output.
The slave select input line is used to select
a slave device in SPI mode. This signal is
multiplexed with PB2.
