Start Condition

A high-to-low transition of SDA with SCL high is a start condition which must precede any other command

(see to Figure 4).

Stop Condition

A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the stop

command will place the ACE24CP02C in a standby power mode (see Figure 4).

Acknowledge (ACK)

All addresses and data words are serially transmitted to and from the ACE24CP02C in 8-bit words. The

ACE24CP02C sends a “0” to acknowledge that it has received each word. This happens during the ninth

clock cycle.

Standby Mode

The ACE24CP02C features a low-power standby mode which is enabled: (a) after a fresh power up, (b)

after receiving a STOP bit in read mode, and (c) after completing a self-time internal programming

operation
