Program Suspend / Resume Mode
Suspend command in Write mode (including Write performed during Erase Suspend) but ignores the command
in other modes. At command input, the address of the bank on which Write is being performed must be specified.
After command input, the device enters Program Suspend Read mode after t

Data Read functions are used, end the functions before inputting the Resume command. On receiving the
Resume command, the device returns to Write mode and resumes output of a Hardware Sequence flag from the
bank to which data are being written.
