(6) UARTCn status register (UCnSTR)
The UCnSTR register is an 8-bit register that displays the UARTCn transfer status and reception error contents.
This register can be read or written in 8-bit or 1-bit units, but the UCnTSF bit is a read-only bit, while the UCnPE,
UCnFE, and UCnOVE bits can both be read and written. However, these bits can only be cleared by writing 0; they
cannot be set by writing 1 (even if 1 is written to them, the value is retained).
The initialization conditions are shown below.
