Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Shadow Break Control Bit.
This is a shadow register for the Break bit (LCR[6]), this can be used to remove
the burden of having to performing a read modify write on the LCR.
This is used to cause a break condition to be transmitted to the receiving device.
If set to one the serial output is forced to the spacing (logic 0) state. When not
in Loopback Mode, as determined by MCR[4], the sout line is forced low until the
Break bit is cleared. If SIR_MODE == Enabled and active (MCR[6] set to one) the
sir_out_n line is continuously pulsed. When in Loopback Mode, the break condition
is internally looped back to the receiver.
Value Description
0x0 No spacing on serial output
0x1 Serial output forced to the spacing
RW 0x0
