18.3.2 CSIB4 and UARTA0 mode switching
CSIB4 function, specify the CSIB4 mode in advance by using the PMC3, PFC3, and PFCE3L registers.
630
In the V850ES/JG3-L, CSIB4 and UARTA0 share pins and therefore cannot be used simultaneously. To use the
Switching the operation mode between CSIB4 and UARTA0 is described below.
Caution Transmission and reception by CSIB4 and UARTA0 are not guaranteed if these operation modes
are switched during transmission or reception. Be sure to disable the serial interface that is not
being used.
