Advanced Feature Control Register 2 bits description
Dual UART with 128-byte FIFOs, IrDA, and XScale VLIO bus interface
Rev. 01 — 23 September 2008
Description
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.
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 RTSA/RTSB or DTRA/DTRB pin to control the
external transceiver.
TXDisable. Disable transmitter.
RXDisable. Disable receiver.
9-bitMode. Enable 9-bit mode or Multidrop (RS-485) mode.
0 = transmit empty interrupt occurs when transmit FIFO falls below the
trigger level or becomes empty.
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.
0 = RTS or DTR is set to 0 by the UART during transmission, and to 1
during reception
1 = RTS or DTR is set to 1 by the UART during transmission, and to 0
during reception
0 = transmitter does not control RTS or DTR signal
1 = transmitter controls RTS or DTR signal
0 = RTSA/RTSB pin is used to control the external transceiver
1 = DTRA/DTRB pin is used to control the external transceiver
0 = transmitter is enabled
1 = transmitter is disabled
0 = receiver is enabled
1 = receiver is disabled
0 = normal RS-232 mode
1 = enable 9-bit mode
