STTBRK: Start Break
0 = No effect.
1 = If break is not being transmitted, start transmission of a break after the characters present in US_THR and the
Transmit Shift Register have been transmitted.
STPBRK: Stop Break
0 = No effect.
1 = If a break is being transmitted, stop transmission of the break after a minimum of one character length and transmit
a high level during 12 bit periods.
STTTO: Start Time-out
0 = No effect.
1 = Start waiting for a character before clocking the time-out counter.
SENDA: Send Address
0 = No effect.
1 = In multi-drop mode only, the next character written to the US_THR is sent with the address bit set.
