/RxD3
The pin function is switched as shown below according to the combination of the RE bit in
SCR of SCI_3, the SMIF bit in SCMR, and the P86DDR bit.
When the ISS14 bit in ISSR16 is set to 1, this pin can be used as the
ExIRQ14
input pin. To
use this pin as the
ExIRQ14
input pin, clear the P86DDR bit to 0.
