Sep 30, 2010
In the V850ES/JG3, 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.
