Advanced Feature Control Register 1 bits description
Advanced Feature Control Register 2 bits description
Single UART with 128-byte FIFOs, IrDA, and XScale VLIO bus interface
Description
SReset. Software reset. A write to this bit will reset the UART. Once the
UART is reset this bit is automatically set to logic 0.
TSR interrupt. Select TSR interrupt mode.
Description
reserved
RTSInvert. Invert RTS or DTR signal in auto 9-bit mode.
RTSCon. Enable the transmitter to control RTS or DTR signal in auto 9-bit
mode.
RS485 RTS/DTR. Select RTS or DTR pin to control the external
transceiver.
TXDisable. Disable transmitter.
RXDisable. Disable receiver.
9-bitMode. Enable 9-bit mode or Multidrop (RS-485) mode.
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 fall below
the trigger level, or becomes empty and the last stop bit has been shift
out the transmit shift register.
logic 0 = RTS or DTR is set to 0 by the UART during transmission, and to
1 during reception
logic 1 = RTS or DTR is set to 1 by the UART during transmission, and to
0 during reception
logic 0 = transmitter does not control RTS or DTR signal
logic 1 = transmitter controls RTS or DTR signal
logic 0 = RTS pin is used to control the external transceiver
logic 1 = DTR pin is used to control the external transceiver
logic 0 = transmitter is enabled
logic 1 = transmitter is disabled
logic 0 = receiver is enabled
logic 1 = receiver is disabled
logic 0 = normal RS-232 mode
logic 1 = enable 9-bit mode
