Alternate Functions Of
Port B
72
ATmega162/V
The Port B pins with alternate functions are shown in
Table 32. 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.
• MOSI – Port B, Bit 5
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 DDB5. When the SPI is
enabled as a Master, the data direction of this pin is controlled by DDB5. When the pin is forced
by the SPI to be an input, the pull-up can still be controlled by the PORTB5 bit.
• SS/OC3B – Port B, Bit 4
SS: Slave Select input. When the SPI is enabled as a slave, this pin is configured as an input
regardless of the setting of DDB4. 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 DDB4. When
the pin is forced by the SPI to be an input, the pull-up can still be controlled by the PORTB4 bit.
OC3B, Output Compare Match B output: The PB4 pin can serve as an external output for the
Timer/Counter3 Output Compare B. The pin has to be configured as an output (DDB4 set (one))
to serve this function. The OC3B pin is also the output pin for the PWM mode timer function.
