•

This device is capable of sixteen byte Page Write operation.

•

When two or more byte data are inputted, the four low order address bits are internally incremented by one after the

receipt of each word. The seven higher order bits of the address (P2 to P0, WA7 to WA4) remain constant.

•

If the master transmits more than sixteen words, prior to generating the STOP condition, the address counter will

“roll over”, and the previous transmitted data will be overwritten.
