automatic write time-out period, the AK6480C/81C stops execution of internal programming and
the device returns to ready status. In this case the word data of the specified address will be
incomplete. When inputting the new instruction after RESET, the CS pin should be set to high
level. When the RESET pin is kept at high level, the Page Write is not executed. This becomes

The CS pin need not be high level during automatic write time-out period ( Busy status).
