Notes
Any form of reset
Bus error returned when reading
the vector table entry,
Failure when saving context using
hardware - bus error returned
Failure when saving context using
hardware - MPU access violation.
Failure when restoring context
using hardware - bus error returned
Failure when restoring context
using hardware - MPU access
violation.
Fault occurred and handler is equal
or higher priority than current,
including fault within fault when
priority does not enable, or
Configurable fault disabled.
Includes SVC, BKPT and other
kinds of faults.
Violation or fault on MPU as a
result of Data access.
Violation/fault on MPU as a result
of instruction address.
Bus error returned because of
instruction fetch. Faults only if
makes it to execute. Branch
shadow can fault and be ignored.
Bus error returned because of data
access, and was precise, points to
instruction.
