Description
UART Transmit Enable
Value Description
1 The transmit section of the UART is enabled.
0 The transmit section of the UART is disabled.
If the UART is disabled in the middle of a transmission, it completes the
current character before stopping.
Note: To enable transmission, the UARTEN bit must also be set.
UART Loop Back Enable
Value Description
1 The UnTx path is fed through the UnRx path.
0 Normal operation.
0
LIN Mode Enable
Value Description
1 The UART operates in LIN mode.
0 Normal operation.
0
High-Speed Enable
Value Description
1 The UART is clocked using the system clock divided by 8.
0 The UART is clocked using the system clock divided by 16.
Note: System clock used is also dependent on the baud-rate divisor
configuration (see page 596) and page 597).
0
End of Transmission
This bit determines the behavior of the TXRIS bit in the UARTRIS
register.
Value Description
1 The TXRIS bit is set only after all transmitted data, including
stop bits, have cleared the serializer.
0 The TXRIS bit is set when the transmit FIFO condition specified
in UARTIFLS is met.
