RDRF = 1
[Clearing conditions]
• Power-on reset or software standby mode
• When 0 is written to ORER after reading ORER = 1

The ORER flag is not affected and retains their previous
values when the RE bit in SCR is cleared to 0.
Framing Error
[Setting condition]
• When the stop bit is 0
[Clearing conditions]
• Power-on reset or software standby mode
• When 0 is written to FER after reading FER = 1
