VDD Supply voltage input, regulated
ON/OFF Module on/off (shutdown)
GND System ground
Note 1: In UART mode the TXD and RXD are used for serial data, and CTS and RTS for flow control (optional).
Note 2: In synchronous mode the SCL (data clock) and SDA (Data input and output) are used for serial data.
The RXEN and TXEN pins are then used to select the operation mode of the device. Signals are active low.
Note 3: The CONFIG pin is used to enter configuration mode (change of default settings).
