Notes
Interrupt exception
handling is kept
waiting until the
executing instruction
ends. If the number of
instruction execution
states is S *
maximum wait time is:
X = S – 1.
However, if BL is set to
1 by instruction
execution or by an
exception, interrupt
exception handling is
deferred until
completion of an
instruction that clears
BL to 0. If the following
instruction masks
interrupt exception
handling, the
processing may be
further deferred.
