VDD = 4.0V, 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. 13.8 CONTROL TIMING (2V) NOTES: 1. VDD = 2.0V, 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.
