4317K–AVR–03/2013

AT90PWM2/3/2B/3B

•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.

•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.
