15.1 Mode Switching of UARTA and Other Serial Interfaces
15.1.1 CSIB4 and UARTA0 mode switching
simultaneously. Set UARTA0 in advance, using the PMC3 and PFC3 registers, before use.
In the V850ES/JG3-L, CSIB4 and UARTA0 are alternate functions of the same pin and therefore cannot be used
Caution The transmit/receive operation of CSIB4 and UARTA0 is not guaranteed if these functions are
switched during transmission or reception. Be sure to disable the one that is not used.
