5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Interrupt and Standby Status)
5.14.7 Programming notes
(1) When executing the RETE instruction without
resetting the interrupt factor flag after an
interrupt has been generated, the same
interrupt will be generated. Consequently, the
interrupt factor flag corresponding to that
routine must be reset (writing "1") in the
interrupt processing routine.
(2) Beware. If the interrupt flags (I0 and I1) have
been rewritten (set to lower priority) prior to
resetting an interrupt factor flag after an
interrupt has been generated, the same
interrupt will be generated again.
(3) An exception processing vector is fixed at 2
bytes, so it cannot specify a branch destination
bank address. Consequently, to branch from
multiple banks to a common exception process-
ing routine, the front portion of an exception
processing routine must be described within the
common area (000000H–007FFFH).
(4) Do not execute the SLP instruction for 2 msec
after a NMI interrupt has occurred (when fOSC1
is 32.768 kHz).
