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 pin Can 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 pin outputs low level; Can be configured as open-drain output or push-pull output; Floating is allowed.
