(5) UARTAn status register (UAnSTR)
The UAnSTR register is an 8-bit register that displays the UARTAn transfer status and reception error contents.
This register can be read or written in 8-bit or 1-bit units, but the UAnTSF bit is a read-only bit, while the
UAnPE, UAnFE, and UAnOVE bits can be both 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 previous value is retained).
The conditions for clearing the UAnSTR register are shown below.

UAnSLS2
UAnRDL
This register can be set when the UAnPWR bit or the UAnTXE bit is 0.
UAnTDL
• The output level of the TXDAn pin can be inverted by using the UAnTDL bit.
• This register can be set when the UAnPWR bit or the UAnTXE bit is 0.
• The input level of the RXDAn pin can be inverted by using the UAnRDL bit.
• This register can be set when the UAnPWR bit or the UAnRXE bit is 0.
