| 1 | GND | - | Ground |
| 2 | GND | - | Ground |
| 3 | GND | - | Ground |
| 4 | GND | - | Ground |
| 5 | M0 | Input(weak pull-up) | Work with M1 & decide the four operating modes;Floating is not allowed, can be ground. |
| 6 | M1 | Input(weak pull-up) | Work with M0 & decide the four operating modes;Floating is not allowed, can be ground. |
| 7 | RXD | Input | TTL UART inputs, connects to external TXD output pin;Can be configured as open-drain or pull-up input. |
| 8 | TXD | Output | TTL UART outputs, connects to external RXD input pinCan be configured as open-drain or push-pull output. |
| 9 | AUX | Output | To wake up the external MCU, during the procedure of self-check initialization, the pinoutputs low level; Can be configured as open-drain output or push-pull output; Floatingis allowed. |
