Notes:
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.
4. The SPD EEPROM WRITE cycle time (
the falling or rising edge of SDA.
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 the pull-up
resistor, and the EEPROM does not respond to its slave address.
