Alternate Functions of
Port B
2466T–AVR–07/10
Table 24. Overriding Signals for Alternate Functions in PA3..PA0
The Port B pins with alternate functions are shown in
Table 25. Port B Pins Alternate Functions
The alternate pin configuration is as follows:
• SCK – 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 SPI is
enabled as a Master, 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.
• MISO – 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
by the SPI to be an input, the pull-up can still be controlled by the PORTB6 bit.
