FE0: Frame Error Flag.
This flag indicates if an invalid (low) STOP bit is detected.
0: Frame Error has not been detected
1: Frame Error has been detected.
RXOV0: Receive Overrun Flag.
This flag indicates new data has been latched into the receive buffer before software has
read the previous byte.
0: Receive overrun has not been detected.
1: Receive Overrun has been detected.
TXCOL0: Transmit Collision Flag.
This flag indicates user software has written to the SBUF0 register while a transmission is in
progress.
0: Transmission Collision has not been detected.
1: Transmission Collision has been detected.
SMOD0: UART0 Baud Rate Doubler Enable.
This bit enables/disables the divide-by-two function of the UART0 baud rate logic for config-
urations described in the UART0 section.
0: UART0 baud rate divide-by-two enabled.
1: UART0 baud rate divide-by-two disabled.
