detected, the reception end interrupt request (INTSR0) 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

Also, when RxD0 functions alternately as a timer input pin, the corresponding timer input pin channels can
also be used for the LIN-bus function. The timer channels in each version of the 78K0R/Ix3 that can be
used for the LIN-bus function in addition to timer channel 7 are shown below.
