(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 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.

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