5 GND power_in Ground: 0V reference.
6 PC2 bidirectional Port C bit 2 I/O with alternate functions T0 (Timer 0 clock input), TXCAN (CAN transmit output) and PCINT10.
7 PC3 bidirectional Port C bit 3 I/O with alternate functions T1 (Timer 1 clock input), RXCAN (CAN receive input), ICP1B and PCINT11.
8 PB0 bidirectional Port B bit 0 I/O with alternate functions MISO (SPI), PSCOUT2A and PCINT0.
9 PB1 bidirectional Port B bit 1 I/O with alternate functions MOSI (SPI), PSCOUT2B and PCINT1.
10 PE1 bidirectional Port E bit 1 I/O with alternate functions XTAL1 (oscillator input), OC0B and PCINT25.
11 PE2 bidirectional Port E bit 2 I/O with alternate functions XTAL2 (oscillator output), ADC0 and PCINT26.
12 PD4 bidirectional Port D bit 4 I/O with alternate functions ADC1, RXD, RXLIN, ICP1A, SCK_A (programming/alternate SPI clock) and PCINT20.
13 PD5 bidirectional Port D bit 5 I/O with alternate functions ADC2, ACMP2 (comparator 2 positive input) and PCINT21.
14 PD6 bidirectional Port D bit 6 I/O with alternate functions ADC3, ACMPN2 (comparator 2 negative input), INT0 and PCINT22.
15 PD7 bidirectional Port D bit 7 I/O with alternate functions ACMP0 (comparator 0 positive input) and PCINT23.
