I2C DC and AC parameters
This section summarizes the operating and measurement conditions, and the DC and AC
characteristics of the device in I2C mode. The parameters in the DC and AC characteristic
tables that follow are derived from tests performed under the measurement conditions
summarized in the relevant tables. Designers should check that the operating conditions in
their circuit match the measurement conditions when relying on the quoted parameters.
