4317J–AVR–08/10
• AMP0- – Bit 3
AMP0-, Analog Differential Amplifier 0 Negative Input Channel.
• ADC5/INT1 – Bit 2
ADC5, Analog to Digital Converter, input channel 5
INT1, External Interrupt source 1. This pin can serve as an external interrupt source to the MCU.
• MOSI/PSCOUT21 – Bit 1
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 DDB1 When the SPI is
enabled as a master, the data direction of this pin is controlled by DDB1. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB1 and PUD bits.
PSCOUT21: Output 1 of PSC 2.
• MISO/PSC20 – Bit 0
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.
PSCOUT20: Output 0 of PSC 2.
