There are does not fit in the receiver side microcomputer ratings results investigated a I2C waveform output timings.

 

Refer the Table 65 of I2C output timing specifications of VYBRIDRSERIESEC Rev7, 11 / 2014 , The P79 No6 No7 MAX values can be disclosed?

 

No6   Data setup time  spec is 2 PER_CLK Cycle=300nsec , but   receiver side microcomputer  spec is normalmode=250nsec and Highspeedmode=100nsec

 

No7 is Start condition setup time (for repeated start condition only) is 20 PER_CLK Cycle=0.3 μ sec, but   receiver side microcomputer  spec is normalmode=4.7 μ sec and Highspeedmode=0.6 μ sec.

 

And , Will also register settings can be adjusted the Data setup time  and Start condition setup time?  .
