CONDITION
The minimum pulse width t
ILIH
is one
internal bus period. The period t
ILIL
should not be less than the number of
t
CYC
cycles it takes to execute the
interrupt service routine plus 21 tcyc
cycles.

IRQ
If after servicing an interrupt the IRQ
pin remains low, then the next interrupt
is recognized. Normally used with wired
OR connection.
Normally used with pull-up resistors for
wired-OR connection.
