is the time from a valid stop condition of a write sequence to the end of the internal clear/write cycle.
STANDBY MODE: The AT24C01A/02/04/08/16 features a low-power standby mode
which is enabled: (a) upon power-up and (b) after the receipt of the Stop bit and the
completion of any internal operations.
MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2-
wire part can be reset by following these steps:
1. Clock up to 9 cycles.
2. Look for SDA high in each cycle while SCL is high.
3. Create a start condition.
