(2) Reset input timing
*1 : Oscillation time of oscillator is time until oscillation reaches 90% of amplitude. It takes several milliseconds to
several dozens of milliseconds on a crystal oscillator, several hundreds of microseconds to several milliseconds
on a FAR/ceramic oscillator, and 0 milliseconds on an external clock.
*2 : Except for MB90F455S/F456S/F457S, MB90455S/456S/457S.
*3 : Refer to "(1) Clock timing" ratings for tCP (internal operation clock cycle time).
