Note:
*The maximum frequency may be limited by different application conditions. Please refer to the application note for
details.
**The period of internal OSC is 9MHz (min.) ~ 13MHz (max.), so the time-out period is 168x76.9ns (12.9us) ~
168x111.1ns (18.6us). Please refer to time out mechanism section.
***The Gray Scale Clock Frequency is 13MHz (max.) when the GCLK=frequency of internal oscillator.
