7647H–AVR–03/12
Atmel ATmega16/32/64/M1/C1
• ADC10/ACMP1/PCINT14 – Bit 6
ADC10, Analog to Digital Converter, input channel 10.
ACMP1, Analog Comparator 1 Positive Input. Configure the port pin as input with the internal
pull-up switched off to avoid the digital port function from interfering with the function of the Ana-
log Comparator.
PCINT14, Pin Change Interrupt 14.
• ADC9/ACMP3/AMP1+/PCINT13 – Bit 5
ADC9, Analog to Digital Converter, input channel 9.
ACMP3, Analog Comparator 3 Positive Input. Configure the port pin as input with the internal
pull-up switched off to avoid the digital port function from interfering with the function of the Ana-
log Comparator.
AMP1+, Analog Differential Amplifier 1 Positive Input Channel. Configure the port pin as input
with the internal pull-up switched off to avoid the digital port function from interfering with the
function of the Analog Amplifier.
PCINT13, Pin Change Interrupt 13.
• ADC8/AMP1-/ACMPN3/PCINT12 – Bit 4
ADC8, Analog to Digital Converter, input channel 8.
AMP1-, Analog Differential Amplifier 1 Negative Input Channel. Configure the port pin as input
with the internal pull-up switched off to avoid the digital port function from interfering with the
function of the Analog Amplifier.
ACMPN3, Analog Comparator 3 Negative Input. Configure the port pin as input with the internal
pull-up switched off to avoid the digital port function from interfering with the function of the Ana-
log Comparator.
PCINT12, Pin Change Interrupt 12.
• PCINT11/T1/RXCAN/ICP1B – Bit 3
T1, Timer/Counter1 counter source.
RXCAN, CAN Rx Data.
ICP1B, Input Capture Pin: The PC3 pin can act as an Input Capture Pin for Timer/Counter1.
PCINT11, Pin Change Interrupt 11.
• PCINT10/T0/TXCAN – Bit 2
T0, Timer/Counter0 counter source.
TXCAN, CAN Tx Data.
PCINT10, Pin Change Interrupt 10.
• PCINT9/PSCIN1/OC1B/SS_A – Bit 1
PCSIN1, PSC 1 Digital Input.
OC1B, Output Compare Match B output: This pin can serve as an external output for the
Timer/Counter1 Output Compare B. The pin has to be configured as an output (DDC1 set “one”)
to serve this function. This pin is also the output pin for the PWM mode timer function.
