NOTES:
1. +4.5 ≤ VDD ≤ +5.5 V, VSS = 0 V, TL ≤ TA ≤ TH, unless otherwise noted
2. The minimum period, tILIL, should not be less than the number of cycle times it takes to execute the interrupt service
routine plus 21 tCYC
.
3. The 500 kHz nominal mask option is available through special order only. Contact your local Motorola sales
representative for detailed ordering information.
