Alternate Functions of Port B
The Port B pins with alternate functions are shown in
Table 9-3.
The alternate pin configuration is as follows:
• PSCOUT22/ICP1/ADC9 – Bit 7
PSCOUT22: Output 2 of PSC 2
ICP1 – Input Capture Pin1: This pin can act as an input capture pin for Timer/Counter1.
ADC9, Analog to Digital Converter, input channel 9
• MISO/ACMP3/ADC8– 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 DDB0. When the SPI is enabled as a slave,
the data direction of this pin is controlled by DDB0. When the pin is forced to be an input, the pull-up can
still be controlled by the PORTB0 and PUD bits.
ACMP3, Analog Comparator 3 Positive Input. Configure the port pin as input with the internal pull-up
switched off to avoid the digital port function from interfering with the function of the Analog
Comparator.
ADC8, Analog to Digital Converter, input channel 8
