MCC beep control register (MCCBCR)
The beep output signal is available in Active Halt mode but has to be disabled to reduce
consumption.
0OIF
Oscillator interrupt flag
This bit is set by hardware and cleared by software reading the MCCSR register. It
indicates when set that the main oscillator has reached the selected elapsed time
(TB1:0).
0: Timeout not reached
1: Timeout reached
Caution: The BRES and BSET instructions must not be used on the MCCSR
register to avoid unintentionally clearing the OIF bit.
