UA0CON is a special function register (SFR) to start/stop communication of the UART.
[Description of Bits]
•
U0EN (bit 0)
The U0EN bit is used to specify the UART communication operation start. When U0EN is set to “1”, UART
communication starts. In transmit mode, this bit is automatically set to “0” at termination of transmission. In
receive mode, receive operation is continued. To terminate reception, set the bit to “0” by software.
U0EN Description
0 Stops communication. (Initial value)
1 Starts communication.
