Read anytime. Write has no meaning or effect.
This bit is controlled by the receiver front end. It is set during the RT1
time period of the start bit search. It is cleared when an idle state is
detected or when the receiver circuitry detects a false start bit
(generally due to noise or baud rate mismatch).
Read anytime. Write has no meaning or affect.
This bit is the ninth serial data bit received when the SCI system is
configured for nine-data-bit operation.
Read or write anytime.
This bit is the ninth serial data bit transmitted when the SCI system is
configured for nine-data-bit operation. When using 9-bit data format
this bit does not have to be written for each data word. The same
value will be transmitted as the ninth bit until this bit is rewritten.
