(2) UARTAn control register 1 (UAnCTL1)
(3) UARTAn control register 2 (UAnCTL2)
(4) UARTAn option control register 0 (UAnOPT0)
Caution Do not set the UAnSRT and UAnSTT bits (to 1) during SBF reception (UAnSRF bit = 1).
For details, see 15.7 (2) UARTAn control register 1 (UAnCTL1).
For details, see 15.7 (3) UARTAn control register 2 (UAnCTL2).
The UAnOPT0 register is an 8-bit register that controls the serial transfer operation of the UARTAn register.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 14H.

• SBF (Sync Break Field) reception is judged during LIN communication.
• The UAnSRF bit is held at 1 when an SBF reception error occurs, and then SBF
• UAnSRF bit is a read-only bit.
• This is the SBF reception trigger bit during LIN communication, and when read,
• Set the UAnSRT bit after setting the UAnPWR bit = UAnRXE bit = 1.
• This is the SBF transmission trigger bit during LIN communication, and when read,
• Set the UAnSTT bit after setting the UAnPWR bit = UAnTXE bit = 1.
