Also read the datasheets of the M62429 for better understanding
For good serial communication to the Renesas chip:
The “low” level of Data and Clock should be max 0.2 x VCC
The “high” level of Data and Clock should be minimum 0.8 x VCC
(Re

ected to our application: low level < 1.08 Vdc and high level > 4.3Vdc)
