UARTCn option control register 0 (UCnOPT0)
The UCnOPT0 register is an 8-bit register that controls the serial transfer operation of the
UARTCn register.
This register can be read or written in 8-bit or 1-bit units.
Reset input sets this register to 14H.

During SBF reception
•
SBF (Sync Brake Field) reception is judged during LIN communication.
•
The UCnSRF bit is held high when a SBF reception error occurs, and then SBF
reception is started again.

SBF reception trigger
•
This is the SBF reception trigger bit during LIN communication, and when read, “0” is
always read. For SBF reception, set the UCnSRT bit (to 1) to enable reception.
•
Set the UCnSRT bit after setting the UCnPWR bit of the UCnCTL0 register to 1 and
the UCnRXE bit of the UCnCTL0 register to 1.

Set the UCnSRT bit after setting the UCnPWR bit of the UCnCTL0 register to 1 and
the UCnRXE bit of the UCnCTL0 register to 1.
