The Port B pins with alternate functions are shown in
Table 15-5.
The alternate pin configuration is as follows:
• MISO/PCINT11 – Port B, Bit7
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 DDB7. When the SPI is
enabled as a Slave, the data direction of this pin is controlled by DDB7. When the pin is forced
by the SPI to be an input, the pull-up can still be controlled by the PORTB7 bit. When not operat-
ing in SPI mode, this pin can serve as an external interrupt source.
PCINT11: Pin Change Interrupt 11. This pin can serve as external interrupt source.
• MOSI/PCINT10 – Port B, Bit6
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 DDB6. When the SPI is
