Asynchronous, UART serial port is applied in our intelligent UART LCD Module with serial port mode of 8n1,i.e. 10 bits for every data transmission: one start bit, 8 data bits(LSB first) and one stop bit.
When powered on, if the terminal I/O 0 pin is high-level or floating, serial port baud rate (from 1200 to 115200 bps) is set by users in advance. (Please refer to Command 0xE0 for more details about the set method.)
When powered on, if the terminal I/O 0 pin is low-level, serial port baud rate is fixed at 921600 bps.
