setup/hold requirements, they will be recognized during the current clock cycle; otherwise the signals will be recognized on the
following cycle. (Refer to “Interrupt Controller Operation” in the Program Control chapter of the
ADSP-2100 Family User’s Manual
, Third Edition, for further informa-
tion on interrupt servicing.)
