Alternate Functions of Port B
The Port B pins with alternate functions are shown in
Table 10-3.The alternate pin configuration is as follows:
PSCOUT01/ADC4/SCK – Bit 7
PSCOUT01: Output 1 of PSC 0.
ADC4, Analog to Digital Converter, input channel 4.
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 to be an input, the pull-up can still be controlled by the
PORTB7 bit.
ADC7/ICP1B/PSCOUT11 – Bit 6
ADC7, Analog to Digital Converter, input channel 7.
ICP1B, Input Capture Pin: The PB6 pin can act as an Input Capture Pin for Timer/Counter1.
PSCOUT11: Output 1 of PSC 1.
ADC6/INT2 – Bit 5
ADC6, Analog to Digital Converter, input channel 6.
INT2, External Interrupt source 2. This pin can serve as an External Interrupt source to the MCU.
APM0+ – Bit 4
AMP0+, Analog Differential Amplifier 0 Positive Input Channel.
AMP0- – Bit 3
AMP0-, Analog Differential Amplifier 0 Negative Input Channel.
