BCFE — Break Clear Flag Enable Bit
This read/write bit enables software to clear status bits by accessing status
registers while the MCU is in a break state. To clear status bits during the break
state, the BCFE bit must be set.
1 = Status bits clearable during break
0 = Status bits not clearable during break
