At record of previously erased chip it is not obligatory to write down cells the containing FFh.

At a parcel of team of permission of programming, the second byte of sequence (53h) will be returned at a parcel of the third byte. Anyway, all four bytes of team have to be sent. If the number 53h is not received back, give a impulse on SCK and repeat team of permission of a. If after 32 attempts the number 53h is not received, the chip is faulty.
