set). When automatic control is enabled, nRTS will be deasserted when the receive FIFO
has space for only one more byte (inhibits transmission from the other device) and will be
asserted if it has space for more than one byte (enables transmission from the other
device). The SC_UARTRTS bit in this register has no effect if this bit is set.
Set this bit to enable using nRTS/nCTS flow control signals. Clear this bit to disable the
signals. When this bit is clear, the UART transmitter will not be inhibited by nCTS.

nRTS is an output to control the flow of serial data sent to the EM35x from another
device. This bit directly controls the output at the nRTS pin (SC_UARTFLOW must be set
and SC_UARTAUTO must be cleared). When this bit is set, nRTS is asserted (pin is low,
'XON', RS232 positive voltage); the other device's transmission is enabled. When this bit is
cleared, nRTS is deasserted (pin is high, 'XOFF', RS232 negative voltage), the other
device's transmission is inhibited.
