*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 μs and several ms. In the external clock, the oscillation time is 0 ms.
