1. To avoid spurious start and stop conditions, a minimum delay is placed between SCL = 1 and
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.

cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to pull-up resis-
tance, and the EEPROM does not respond to its slave address.
