BCFE — Break Clear Flag Enable Bit
In some module registers, this read/write bit will enable software to
clear status bits by accessing status registers only while the MCU is
in a break state. To clear status bits during the break state, the BCFE
bit must be set.This operation is important for modules with status bits
which can be cleared only by being read. See the register
descriptions in each module for additional details.
1 = Status bits clearable during break
0 = Status bits not clearable during break
