Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TEST | input | JTAG test pin for selecting test mode on Port1 pins; device protection fuse connected to this terminal. |
| 2 | VCC | power_in | Power supply input; range 1.8V to 3.6V for normal operation or 2.2V to 3.6V for flash programming. |
| 3 | P2.5/CA5 | bidirectional | General-purpose digital I/O pin; functions as Comparator_A+ CA5 input when selected via control registers. |
| 4 | VSS | power_in | Ground reference connection for analog and digital circuits. |
| 5 | XOUT/P2.7/CA7 | bidirectional | Crystal oscillator output terminal or general-purpose I/O pin; functions as Comparator_A+ CA7 input. |
| 6 | XIN/P2.6/CA6 | bidirectional | Crystal oscillator input terminal or general-purpose I/O pin; functions as Comparator_A+ CA6 input. |
| 7 | RST/NMI | input | Reset input or nonmaskable interrupt input; requires minimum 2μs pulse width. |
| 8 | P2.0/ACLK/CA2 | bidirectional | General-purpose I/O pin; outputs auxiliary clock (ACLK) or serves as Comparator_A+ CA2 input. |
| 9 | P2.1/INCLK/CA3 | bidirectional | General-purpose I/O pin; receives Timer_A INCLK input or serves as Comparator_A+ CA3 input. |
| 10 | P2.2/CAOUT/TA0/CA4 | bidirectional | General-purpose I/O pin; outputs Comparator_A+ result or Timer_A TA0, receives BSL data, or serves as CA4 input. |
| 11 | P2.3/TA1/CA0 | bidirectional | General-purpose I/O pin; outputs Timer_A compare Out1 or serves as Comparator_A+ CA0 input. |
| 12 | P2.4/TA2/CA1 | bidirectional | General-purpose I/O pin; outputs Timer_A compare Out2 or serves as Comparator_A+ CA1 input. |
| 13 | P1.0/TACLK | bidirectional | General-purpose I/O pin; receives Timer_A TACLK clock input when P1SEL.0 = 1. |
| 14 | P1.1/TA0 | bidirectional | General-purpose I/O pin; receives Timer_A CCI0A capture input, outputs compare Out0, or transmits BSL data. |
| 15 | P1.2/TA1 | bidirectional | General-purpose I/O pin; receives Timer_A CCI1A capture input or outputs compare Out1. |
| 16 | P1.3/TA2 | bidirectional | General-purpose I/O pin; receives Timer_A CCI2A capture input or outputs compare Out2. |
| 17 | P1.4/SMCLK/TCK | bidirectional | General-purpose I/O pin; outputs sub-main clock (SMCLK) or receives JTAG test clock (TCK) input. |
| 18 | P1.5/TA0/TMS | bidirectional | General-purpose I/O pin; outputs Timer_A compare Out0 or receives JTAG test mode select (TMS) input. |
| 19 | P1.6/TA1/TDI/TCLK | bidirectional | General-purpose I/O pin; outputs Timer_A compare Out1 or receives JTAG test data input (TDI) or clock input. |
| 20 | P1.7/TA2/TDO/TDI | bidirectional | General-purpose I/O pin; outputs Timer_A compare Out2 or JTAG test data output (TDO), or receives test data input (TDI). |
