ATmega8HVA/16HVA
Alternate Functions of Port A
The Port A pins with alternate functions are shown in
Table 15-3.
The alternate pin configuration is as follows:
• ADC0/ SNGD/ T0 – Port A, Bit 0
Voltage Analog to Digital Converter (Channel 0), Signal Ground for Voltage Analog to Digital
Converter or Timer/Counter0 Counter Source.
• ADC1/ SNGD/ T1 – Port A, Bit 1
Voltage Analog to Digital Converter (Channel 1) , Signal Ground for Voltage Analog to Digital
Converter or Timer/Counter1 Counter Source.
