9.3.3 Alternate Functions of Port C
The Port C pins with alternate functions are shown in Table 9-6.
Note: On the engineering samples (Parts marked AT90PWM324), the ACMPN3 alternate function is not
located on PC4. It is located on PE2.
The alternate pin configuration is as follows:
• D2A/AMP2+/PCINT15 – Bit 7
D2A, Digital to Analog output
AMP2+, Analog Differential Amplifier 2 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 Amplifier.
PCINT15, Pin Change Interrupt 15.
