Cleared due to user read of RCREGx
Note 1: The EUSARTx remains in Idle while the WUE bit is set.

Note 1
Cleared due to user read of RCREGx
Note 1: If the wake-up event requires long oscillator warm-up time, the auto-clear of the WUE bit can occur before the oscillator is ready. This
sequence should not depend on the presence of Q clocks.
2: The EUSARTx remains in Idle while the WUE bit is set.
