1. Initiate clock stretching, which is an optional SMBus bus feature.
2.
A timeout condition can only be ensured if SCL is driven low for
Standby mode and is ready to receive a new START condition. If
internal state remains unchanged.

3. Measured during characterization, not tested in production.
4. To avoid spurious START and STOP conditions, a minimum delay is placed between the falling edge of SCL and the falling
or rising edge of SDA.
