Alternate Functions of Port B
The Port B pins with alternate functions are shown in Table 14-6.
The alternate pin configuration is as follows:
SCK/OC3B/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.
OC3B, Output Compare Match B output: The PB7 pin can serve as an external output for the
Timer/Counter3 Output Compare. The pin has to be configured as an output (DDB7 set “one”) to
serve this function. The OC3B pin is also the output pin for the PWM mode timer function.
PCINT15, Pin Change Interrupt source 15: The PB7 pin can serve as an external interrupt
source.
MISO/OC3A/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.
