17.3 Mode Switching of UARTC and Other Serial Interfaces
17.3.1 UARTC0 and CSIB1 mode switching
simultaneously. Set UARTC0 in advance, using the PMC9 and PFC9 registers, before use.
In the
Caution The transmit/receive operation of CSIF4 and UARTC0 is not guaranteed if these functions are
μ
PD70F3792, 70F3793, CSIB1 and UARTC0 share the same pins and therefore cannot be used
switched during transmission or reception. Be sure to disable the one that is not used.

SIB1 and RXDC0 are alternate functions. When using the pin as the SIB1 pin,
disable RXDC0 pin detection, which is the alternate function. (Clear the
UC0CTL0.UC0PWR bit to 0.) Also, when using the pin as the RXDC0 pin, disable
SIB1 pin, which is the alternate function. (Clear the CB1CTL0.CB1PWR bit to 0.)
