3. As measured from 100 mV differential crosspoints of last and first edges of burst.
4. Operating data period during Out-Of-Band burst transmissions.
1. t134 has a minimum timing for I
2. A device will timeout when any clock low exceeds this value.
3. t137 is the cumulative time a slave device is allowed to extend the clock cycles in one message from the initial
4. t138 is the cumulative time a master device is allowed to extend its clock cycles within each byte of a message
