Rev. 04 — 14 January 2008
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
