Alternate Functions of Port B
The Port B pins with alternate functions are shown in
Table 11-6.
The alternate pin configuration is as follows:
• SCK/PCINT15 – Port B, Bit 7
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 DDB7. When the SPI0 is
enabled as a master, the data direction of this pin is controlled by DDB7. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB7 bit.
PCINT15, Pin Change Interrupt source 15: The PB7 pin can serve as an external interrupt
source.
• MISO/PCINT14 – Port B, Bit 6
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 DDB6. When the SPI is
enabled as a slave, the data direction of this pin is controlled by DDB6. When the pin is forced to
be an input, the pull-up can still be controlled by the PORTB6 bit.
PCINT14, Pin Change Interrupt source 14: The PB6 pin can serve as an external interrupt
source.
