2.4 AC Characteristics
Note The following conditions are required for low voltage interface when EVDD0 < VDD
1.8 V EVDD0 < 2.7 V: MIN. 125 ns
1.6 V EV
DD0 < 1.8 V: MIN. 250 ns
Remark fMCK: Timer array unit operation clock frequency
(Operation clock to be set by the CKSmn bit of timer mode register mn (TMRmn). m: Unit number (m = 0, 1), n: Channel
number (n = 0 to 3))
(TA = -40 to +85 C, 1.6 V EVDD0 = EVDD1 VDD 5.5 V, VSS = EVSS0 = EVSS1 = 0 V)
