Description
reserved
Sleep RXLow. Program RX input to be edge-sensitive or level-sensitive.
reserved
RTS/CTS mapped to DTR/DSR. Switch the function of RTS/CTS to
DTR/DSR.
SReset. Software Reset. A write to this bit will reset the UART. Once the
UART is reset this bit is automatically set to 0.
TSR Interrupt. Select TSR interrupt mode
logic 0 = RX input is level-sensitive. If RX pin is LOW, the UART will
not go to sleep. Once the UART is in Sleep mode, it will wake up if RX
pin goes LOW.
logic 1 = RX input is edge-sensitive. UART will go to sleep even if RX
pin is LOW, and will wake up when RX pin toggles.
logic 0 = RTS and CTS signals are used for hardware flow control.
logic 1 = DTR and DSR signals are used for hardware flow control.
RTS and CTS retain their functionality.
logic 0 = transmit empty interrupt occurs when transmit FIFO falls
below the trigger level or becomes empty.
logic 1 = transmit empty interrupt occurs when transmit FIFO falls
below the trigger level, or becomes empty and the last stop bit has
been shifted out of the Transmit Shift Register.
