6.3 Acknowledge Polling
6.4 Write Protection
Acknowledge polling is used to know the completion of the write cycle in the E
After the E
and no response is made to the signal transmitted by the master device.
Accordingly the master device can recognize the completion of the write cycle in the E
a response from the slave device after transmitting the start condition, the device address and the
read/write instruction code to the E
That is, if the E
E
It is recommended to use the read instruction "1" as the read/write instruction code transmitted by the
master device.
Write protection is available in the S-24CS01A/02A/04A/08A. When the WP pin is connected to the V
write operation to memory area is forbidden at all.
When the WP pin is connected to the GND, the write protection is invalid, and write operation in all memory
area is available. There is no need for using write protection, the WP pin should be connected to the GND.
The write protection is valid in the operating voltage range.
