Command Interface

Instructions, made up of commands written in cy-

cles, can be given to the Program/Erase Controller

through a Command Interface (C.I.). For added

data protection, program or erase execution starts

after 4 or 6 cycles. The first, second,fourth and fifth

cycles are used to input Coded cycles to the C.I.

This Coded sequence is the same for all Pro-

gram/Erase Controller instructions. The ’Com-

mand’ itself and its confirmation, when applicable,

are given on the third, fourth or sixth cycles. Any

incorrect command or any improper command se-

quence will reset the device to Read Array mode.
