NOTES
1
IRQx=IRQ0, IRQ1, and IRQ2.
2
If IRQx and FI inputs meet t
and t
setup/hold requirements, they will be recognized during the current clock cycle; otherwise they will be recognized
IFS
IFH
during the following cycle. (Refer to the “Interrupt Controller” section in Chapter 3, Program Control, of the ADSP-2100 Family User’s Manual for further
information on interrupt servicing.)
3
Edge-sensitive interrupts require pulse widths greater than 10 ns. Level-sensitive interrupts must be held low until serviced.
