1. +2.7 ≤ VDD ≤ +3.3 V, VSS = 0 V, TL ≤ TA ≤ TH, unless otherwise noted
2. The 500 kHz nominal mask option is available through special order only. Contact your local Freescale sales representative
for detailed ordering information. Not offered with the RC oscillator option.
3. 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.
