(1) Clock Timing
(VCC5
= 5 V ± 10%, VCC3 = 3.3 V ± 5%, VSS = AVSS = AVRL = 0 V, TA = 0 °C to +70 °C)
*1 : Frequency fluctuation rate indicates the maximum fluctuation ratio from the setting central frequency during
locking in case of doubling.
*2 : This is the value when 10 MHz, which is the minimum value of the clock frequency, is input to X0 and 1/2 cycle
of the oscillation circuit and gearing of 1/8 are used.
*3 : This is the value when doubler is used with a 50 MHz CPU.
