SWITCHING CHARACTERISTICS over COMMERCIAL and INDUSTRIAL operating ranges
Interrupt Acknowledge Cycle (20 MHz and 25 MHz)
Notes:
All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA, unless otherwise noted. All output test conditions
are with C
a Testing is performed with equal loading on referenced pins.
b This parameter applies to the INTA1–INTA0 signals.
