Alternate Functions of Port C
The Port C pins with alternate functions are shown in
Table 9-6.
Note:
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.
On the engineering samples (Parts marked AT90PWM324), the ACMPN3 alternate function is
not located on PC4. It is located on PE2.
