1 | M0 | Input(weak pull-up) | Work with M1 & decide the four operating modes. Floating is not allowed, can be ground. |
2 | M1 | Input(weak pull-up) | Work with M0 & decide the four operating modes. Floating is not allowed, can be ground. |
3 | RXD | Input | TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input |
4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin.Can be configured as open-drain or push-pull output |
5 | AUX | Output | To indicate module's working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as open-drain output or push-pull output (floating is allowed). |
