Meeting setup and hold guarantees interrupts will be latched in that cycle. Meeting
the pulse width is not necessary if the setup and hold is met. Likewise, meeting the
setup and hold is not necessary if the pulse width is met. See the Hardware Config-
uration chapter of the
ADSP-21020 User’s Manual
from Analog Devices for interrupt
servicing information.
