1. To avoid spurious start and stop conditions, a minimum delay is placed between SCL = 1
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.
4. The SPD EEPROM WRITE cycle time (
and the falling or rising edge of SDA.
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 resistance, and the EEPROM does not respond to its slave address.
