Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power supply ground reference pin for the microcontroller. |
| 2 | P1.0 | bidirectional | General-purpose I/O port that can also function as external crystal oscillator input (XIN), external interrupt 0_1 input, or comparator 2 positive input (CMP2+). |
| 3 | P1.1 | bidirectional | General-purpose I/O port, ADC14 analog input channel, external crystal oscillator output (XOUT), external interrupt 1_1 input, or comparator 3 positive input (CMP3+). |
| 4 | P2.7 | bidirectional | General-purpose I/O port, ADC15 analog input channel, external reset input pin (RST), or external interrupt 15 input; default factory configuration sets as reset pin with Schmitt input and pull-up. |
| 5 | P2.6 | bidirectional | General-purpose I/O port, external interrupt 14 input, port low voltage detection input (PLVD) at 1.2V threshold, or comparator negative input (CMP-). |
| 6 | P2.5 | bidirectional | General-purpose I/O port, ADC13 analog input channel, external interrupt 13 input, or comparator 1 positive input (CMP1+). |
| 7 | P2.4 | bidirectional | General-purpose I/O port, ADC12 analog input channel, or external interrupt 12 input. |
| 8 | P2.3 | bidirectional | General-purpose I/O port, ADC11 analog input channel, or external interrupt 11 input. |
| 9 | P2.2 | bidirectional | General-purpose I/O port, ADC10 analog input channel, or external interrupt 10 input. |
| 10 | P2.1 | bidirectional | General-purpose I/O port, ADC9 analog input channel, external interrupt 9 input, or I2C two-wire mode SDA data input/output. |
| 11 | P2.0 | bidirectional | General-purpose I/O port, ADC8 analog input channel, or external interrupt 8 input. |
| 12 | P0.7 | bidirectional | General-purpose I/O port, ADC7 analog input channel, or external interrupt 7 input. |
| 13 | P0.6 | bidirectional | General-purpose I/O port, ADC6 analog input channel, or external interrupt 6 input. |
| 14 | P0.5 | bidirectional | General-purpose I/O port, ADC5 analog input channel, or external interrupt 5 input. |
| 15 | P0.4 | bidirectional | General-purpose I/O port, ADC4 analog input channel, external ADC reference voltage input/output (Vref), or external interrupt 4 input. |
| 16 | P0.3 | bidirectional | General-purpose I/O port, ADC3 analog input channel, external interrupt 3 input, or SPI serial clock input (SCK). |
| 17 | P0.2 | bidirectional | General-purpose I/O port, ADC2 analog input channel, external interrupt 2 input, or PWM2 fault detection input (FLT2); supports debouncing via P00DBC register. |
| 18 | P0.1 | bidirectional | General-purpose I/O port, ADC1 analog input channel, external interrupt 1 input, or PWM1 fault detection input (FLT1); supports debouncing via P01DBC register. |
| 19 | P0.0 | bidirectional | General-purpose I/O port, ADC0 analog input channel, external interrupt 0 input, or PWM0 fault detection input (FLT0); supports debouncing via P00DBC register. |
| 20 | VDD | power_in | Power supply input pin; operating voltage range is 2.9V to 5.5V; decouple with ≥0.1µF capacitor to GND for system stability. |
