16.3 Mode Switching of UARTA and Other Serial Interfaces
16.3.1 UARTA0 and CSIB4 mode switching
UARTA0 function, specify the UARTA0 mode in advance by using the PMC3, PFC3, and PFCE3 registers.
552
In the V850ES/JG3-L, UARTA0 and CSIB4 share pins and therefore cannot be used simultaneously. To use the
Switching the operation mode between UARTA0 and CSIB4 is described below.
Caution Transmission and reception by UARTA0 and CSIB4 are not guaranteed if these operation modes
are switched during transmission or reception. Be sure to stop the serial interface that is not
being used.
