SC_UARTAUTO: Set this bit to enable automatic nRTS control by hardware (SC_UARTFLOW
must also be 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.
SC_UARTFLOW: 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.
SC_UARTODD: If parity is enabled, specifies the kind of parity.
0: Even parity.
SC_UARTPAR: Specifies whether to use parity bits.
0: Don't use parity.
SC_UART2STP: Number of stop bits transmitted.
0: 1 stop bit.
SC_UART8BIT: Number of data bits.
0: 7 data bits.
SC_UARTRTS: nRTS is an output to control the flow of serial data sent to the STM32W108
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.
