ATmega16HVB/32HVB
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/SGND/PCINT0 – Port A, Bit0
ADC0: Voltage ADC Channel0. This pin can serve as Channel 0 Input for the Voltage ADC.
SGND: Voltage ADC Signal Ground. This pin can serve as Channel 1 Signal Ground for the
Voltage ADC.
PCINT0. Pin Change Interrupt 0. This pin can serve as external interrupt source.
• ADC1/SGND/PCINT1 – Port A, Bit1
ADC1: Voltage ADC Channel 1: This pin can serve as Channel 1 for the Voltage ADC.
SGND: Voltage ADC Signal Ground. This pin can serve as Channel 0 Signal Ground for the
Voltage ADC.
PCINT1: Pin Change Interrupt 1. This pin can serve as external interrupt source.
• T0/PCINT2 – Port A, Bit2
T0: Timer/Counter0. This pin can serve as Timer/Counter0 clock source.
PCINT2: Pin Change Interrupt 2. This pin can serve as external interrupt source.
• T1/PCINT3 – Port A, Bit3
T1: Timer/Counter1. This pin can serve as Timer/Counter1 clock source.
PCINT3: Pin Change Interrupt 3.
These pins can serve as external interrupt source.
