No. Item Direction Application
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 wake 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).
