14.3.4 Alternate Functions of Port E
The Port E pins with alternate functions are shown in Table 14-12 .
Note: 1. 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:
• PCINT26/XTAL2/ADC0 – Bit 2
