*1 : Refer to “ (2) Source Clock/Machine Clock” for tMCLK.
*2 : Oscillation start time of oscillator is the time that the amplitude reaches 90 %. In the crystal oscillator, the
oscillation time is between several ms and tens of ms. In ceramic oscillators, the oscillation time is between
hundreds of
s and several ms. In the external clock, the oscillation time is 0 ms.
