Through these pins, serial data is transmitted and received as frames comprising:
●
An Idle Line prior to transmission or reception
●
A start bit
●
A data word (8 or 9 bits) least significant bit first
●
A Stop bit indicating that the frame is complete.
This interface uses two types of baud rate generator:
●
