PCINT4, Pin Change Interrupt source 4: The PB4 pin can serve as an external interrupt
source.
• MISO/PDO/PCINT3 – Port B, Bit 3
MISO: Master Data input, Slave Data output pin for SPI channel. When the SPI is
enabled as a master, this pin is configured as an input regardless of the setting of
DDB3. When the SPI is enabled as a slave, the data direction of this pin is controlled by
DDB3. When the pin is forced to be an input, the pull-up can still be controlled by the
PORTB3 bit.
PDO, SPI Serial Programming Data Output. During Serial Program Downloading, this
pin is used as data output line (see section
details).
PCINT3, Pin Change Interrupt source 3: The PB3 pin can serve as an external interrupt
source.
• MOSI/PDI/PCINT2 – Port B, Bit 2
MOSI: SPI Master Data output, Slave Data input for SPI channel. When the SPI is
enabled as a slave, this pin is configured as an input regardless of the setting of DDB2.
When the SPI is enabled as a master, the data direction of this pin is controlled by
DDB2. When the pin is forced to be an input, the pull-up can still be controlled by the
PORTB2 bit.
PDI, SPI Serial Programming Data Input. During Serial Program Downloading, this pin
is used as data input line (see section
PCINT2, Pin Change Interrupt source 2: The PB2 pin can serve as an external interrupt
source.
• SCK/PCINT1 – Port B, Bit 1
SCK: Master Clock output, Slave Clock input pin for SPI channel. When the SPI is
enabled as a slave, this pin is configured as an input regardless of the setting of DDB1.
When the SPI0 is enabled as a master, the data direction of this pin is controlled by
DDB1. When the pin is forced to be an input, the pull-up can still be controlled by the
PORTB1 bit.
PCINT1, Pin Change Interrupt source 1: The PB1 pin can serve as an external interrupt
source.

SS
as an input regardless of the setting of DDB0. As a slave, the SPI is activated when this
pin is driven low. When the SPI is enabled as a master, the data direction of this pin is
controlled by DDB0. When the pin is forced to be an input, the pull-up can still be
controlled by the PORTB0 bit.

the overriding signals shown in
SLAVE OUTPUT constitute the MISO signal, while MOSI is divided into SPI MSTR
OUTPUT and SPI SLAVE INPUT.
PCINT0, Pin Change Interrupt source 0: The PB0 pin can serve as an external interrupt
source.
