PB2
GPIO Port B
Bidirectional
This pin can be used for GPIO. 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.
SS
Slave Select
GPIO Port B
Input, Active Low
Bidirectional
The slave select input line is used to
select a slave device in SPI mode.
This signal is multiplexed with PB2.

92
93
PB3
This pin can be used for GPIO. 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.
SCK
PB4
SPI Serial
Clock
Bidirectional
Bidirectional
SPI serial clock. This signal is multiplexed
with PB3.
GPIO Port B
This pin can be used for GPIO. 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.
T4_OUT
PB5
Timer 4 Out
GPIO Port B
Output
Programmable Reload Timer 4 timer-out
signal. This signal is multiplexed with PB4.
Bidirectional
This pin can be used for GPIO. 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.
T5_OUT
Timer 5 Out
Output
Programmable Reload Timer 5 timer-out
signal. This signal is multiplexed with PB5.
