Pin No.	Pin Item	Pin Direction	Pin 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.
