Transmission Enable Bit (bit 0)
0: Disable the transmit process
1: Enables the transmit process. If the transmit process is disabled (TEN cleared)
during transmission, the transmit will not stop until completed.
Receive Enable Bit (bit 1)
0: Disable the receive process
1: Enables the receive process. If the receive process is disabled (REN cleared)
during reception, the receive will not stop until completed.
Transmission Initialization Bit (bit 2)
0: No action.
1: Resets the UART transmit status register bits as well as stopping the transmission
operation. The TEN bit must be set and the transmit buffer reloaded in order to transmit
again. The TIN is automatically reset one cycle after TIN is set.
Receive Initialization Bit (bit 3)
0: No action.
1: Clears the UART receive status flags and the REN bit. If RIN is set during receive in
progress, receive operation is aborted. The RIN bit is automatically reset one cycle
after RIN is set.
Transmit Interrupt Source Selection Bit (bit 4)
0: Transmit interrupt occurs when the Transmit Buffer Empty flag is set.
1: Transmit interrupt occurs when the Transmit Complete flag is set.
Clear-to-Send (CTS) Enable Bit (bit 5)
0: CTS function is disabled, P8
6
(or P8
2
) is used as GPIO pin.
1: CTS function is enabled, P8
(or P8
2
) is used as CTS input.
Request-to-Send (RTS) Enable Bit (bit 6)
0: RTS function is disabled, P8
7
(or P8
3
) is used as GPIO pin.
1: RTS function is enabled, P8
(or P8
3
) is used as RTS output.
UART Address Mode Enable Bit (bit 7)
0: Address Mode disabled.
1: Address Mode enabled.
