NOTE:
1. To avoid spurious START and STOP conditions, a minimum delay is placed between SCL = 1 and the falling or rising
edge of SDA.
2. This parameter is sampled.
3. For a restart condition, or following a WRITE cycle.
4. The SPD EEPROM WRITE cycle time (^tWRC) is the time from a valid stop condition of a write sequence to the end of
the EEPROM internal erase/program cycle. During the WRITE cycle, the EEPROM bus interface circuit is disabled, SDA
remains HIGH due to pull-up resistor, and the EEPROM does not respond to its slave address.
