the reception end interrupt request (INTSR3) is generated. When data of low levels of 11 bits or more is detected
as SBF, it is judged that SBF reception has been correctly completed. If data of low levels of less than 11 bits is
detected as SBF, it is judged that an SBF reception error has occurred, and the system returns to the SBF
