Framing error
A framing error is detected when:
●

When the framing error is detected:
●

●
The FE bit is reset by a SCISR register read operation followed by a SCIDR register read
operation.
The stop bit is not recognized on reception at the expected time, following either a de-
synchronization or excessive noise.
A break is received.
The FE bit is set by hardware.
Data is transferred from the Shift register to the SCIDR register.
No interrupt is generated. However this bit rises at the same time as the RDRF bit
which itself generates an interrupt.
