The DS1200-3 power supply might apply clock stretching. An addressed slave power supply may hold the
clock line (SCL) low after receiving (or sending) a byte, indicating that it is not yet ready to process more data.
The system master that is communicating with the power supply will attempt to raise the clock to transfer the next bit, but
must verify that the clock line was actually raised. If the power supply is clock stretching, the clock line will still be low
(because the connections are open-drain).
The maximum time out condition for clock stretching for DS1200-3 is 100 microseconds.
