Chip Select (CS)
The device is selected when the CS input is LOW. The
current counter value is stored in nonvolatile memory
when CS is returned HIGH while the INC input is also
HIGH. After the store operation is complete the X9C102/
103/104/503 device will be placed in the low power
standby mode until the device is selected once again.
