ATmega406
Alternate Functions of Port A
The Port A has an alternate function as input pins to the Voltage ADC.
Table 13-3.
The alternate pin configuration is as follows:
• ADC4/INT3:0/PCINT7:4 – Port A, Bit 7:4
Analog to Digital Converter, Channel 4.
INT3 - INT0, External Interrupt Sources 3:0. The PA7:4 pins can serve as external interrupt
sources to the MCU.
PCINT7 - PCINT4, Pin Change Interrupt Sources 7:4. The PA7:4 pins can serve as external
interrupt sources to the MCU.
• ADC3:0/PCINT3:0 – Port A, Bit 3:0
Analog to Digital Converter, Channels 3:0.
PCINT3 - PCINT0, Pin Change Interrupt Sources 3:0. The PA3:0 pins can serve as external
interrupt sources to the MCU.
