• BASEPRI
Priority mask bits:
0x0000 = no effect
Nonzero = defines the base priority for exception processing.
The processor does not process any exception with a priority value greater than or equal to BASEPRI.
This field is similar to the priority fields in the interrupt priority registers. The processor implements only bits[7:4] of this field,
bits[3:0] read as zero and ignore writes. See
that higher priority field values correspond to lower exception priorities.

The BASEPRI register defines the minimum priority for exception processing. When BASEPRI is
set to a nonzero value, it prevents the activation of all exceptions with same or lower priority
level as the BASEPRI value. See the register summary in
butes. The bit assignments are:
