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
