Pinout
| Pin | Name | Type | Function |

| 2 | PE0 | bidirectional | Port E bit 0 used as RESET input when the RSTDISBL fuse is unprogrammed (a low level longer than the minimum pulse length in Table 9-1 generates a reset, shorter pulses are not guaranteed) or as an I/O pin when RSTDISBL is programmed; also OCD on-chip debug I/O. |
| 3 | PD1 | bidirectional | Port D bit 1 with internal pull-up; alternate functions are PSCIN0 (PSC 0 digital input) and CLKO (system clock output). |

| 10 | PE1 | bidirectional | Port E bit 1; depending on the clock selection fuse settings it is the input to the inverting oscillator amplifier and the internal clock operating circuit (XTAL1), and it also serves as OC0B (Timer 0 output compare B). |
| 11 | PE2 | bidirectional | Port E bit 2; depending on the clock selection fuse settings it is the output of the inverting oscillator amplifier (XTAL2), and it also serves as ADC0 analog input channel 0. |

| 17 | AVCC | power_in | Analog supply voltage for the A/D converter; it must be connected to VCC even if the ADC is not used, and through a low-pass filter if the ADC is used. |
| 18 | AGND | power_in | Analog ground, 0 V reference for the analog part. |
| 19 | AREF | passive | Analog reference for the A/D converter (reference voltage of the ADC); as an output it can be used by external analog circuitry. |
| 20 | PB3 | bidirectional | Port B bit 3 with internal pull-up; alternate function is AMP0- (analog differential amplifier 0 negative input channel). |
| 21 | PB4 | bidirectional | Port B bit 4 with internal pull-up; alternate function is AMP0+ (analog differential amplifier 0 positive input channel). |
| 22 | PB5 | bidirectional | Port B bit 5 with internal pull-up; alternate functions are ADC6 (analog input channel 6) and INT2 (external interrupt 2). |
