Note:
* wd: is wire delay , which is dependent on wire distance and wire material.
**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.
****Users have to leave more time than the maximum error detection time for the error detection.
*****The maximum frequency may be limited by different application conditions. Please refer to the application note
for details.
