| 3 | P1.1/TA0.0/CA1 | bidirectional | General-purpose digital I/O pin, also Timer0_A CCI0A capture input or Out0 compare output, and Comparator_A+ CA1 input. |
| 4 | P1.2/TA0.1/CA2 | bidirectional | General-purpose digital I/O pin, also Timer0_A CCI1A capture input or Out1 compare output, and Comparator_A+ CA2 input. |
| 5 | P1.3/CAOUT/CA3 | bidirectional | General-purpose digital I/O pin, also Comparator_A+ output CAOUT and Comparator_A+ CA3 input. |
| 6 | P1.4/SMCLK/TA0.2/CA4/TCK | bidirectional | General-purpose digital I/O pin, also SMCLK signal output, Timer0_A CCI2A capture input or Out2 compare output, Comparator_A+ CA4 input, and JTAG test clock TCK input for device programming and test. |
| 7 | P1.5/TA0.0/SCLK/CA5/TMS | bidirectional | General-purpose digital I/O pin, also Timer0_A Out0 compare output, USI clock SCLK (input in I2C mode, clock input/output in SPI mode), Comparator_A+ CA5 input, and JTAG test mode select TMS input. |
| 8 | P1.6/TA0.1/SDO/SCL/CA6/TDI/TCLK | bidirectional | General-purpose digital I/O pin, also Timer0_A Out1 compare output, USI data output SDO in SPI mode or I2C clock SCL, Comparator_A+ CA6 input, and JTAG TDI/TCLK input for device programming and test. |
| 9 | P1.7/CAOUT/SDI/SDA/CA7/TDO/TDI | bidirectional | General-purpose digital I/O pin, also Comparator_A+ output, USI data input SDI in SPI mode or I2C data SDA, Comparator_A+ CA7 input, and JTAG TDO/TDI test data output or input, selected via JTAG instruction. |
| 10 | RST/NMI/SBWTDIO | input | Reset pin, also nonmaskable interrupt input NMI and Spy-Bi-Wire test data input/output during programming and test. |
| 11 | TEST/SBWTCK | input | Selects test mode for JTAG pins on port 1 (the device protection fuse is connected to TEST), and is the Spy-Bi-Wire test clock input during programming and test. |
| 12 | XOUT/P2.7 | bidirectional | Output terminal of the crystal oscillator, also general-purpose digital I/O P2.7; if used as an input, excess current flows until P2SEL.7 is cleared. |
