ATmega325P/3250P

PCINT12, Pin Change Interrupt Source 12: The PB4 pin can serve as an external interrupt

source.

• MISO/PCINT11 – Port B, Bit 3

MISO: Master Data input, Slave Data output pin for SPI. 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.

PCINT11, Pin Change Interrupt Source 11: The PB3 pin can serve as an external interrupt

source.

• MOSI/PCINT10 – Port B, Bit 2

MOSI: SPI Master Data output, Slave Data input for SPI. 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.

PCINT10, Pin Change Interrupt Source 10: The PB2 pin can serve as an external interrupt

source.

• SCK/PCINT9 – Port B, Bit 1

SCK: Master Clock output, Slave Clock input pin for SPI. When the SPI is enabled as a Slave,

this pin is configured as an input regardless of the setting of DDB1. When the SPI 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.

PCINT9, Pin Change Interrupt Source 9: The PB1 pin can serve as an external interrupt source.

•SS/PCINT8 – Port B, Bit 0

SS: Slave Port Select input. When the SPI is enabled as a Slave, this pin is configured 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

PCINT8, Pin Change Interrupt Source 8: The PB0 pin can serve as an external interrupt source.
