Bulk Erase (BE)
The Bulk Erase (BE) instruction sets all bits to '1' (FFh). Before it can be accepted, a Write
Enable (WREN) instruction must previously have been executed.
Apart form the parallelizing of the instruction code on the four pins DQ0, DQ1, DQ2 and
DQ3, the instruction functionality is exactly the same as the Bulk Erase (BE) instruction of
the Extended SPI protocol, please refer to
details.

Program/Erase Suspend
The Program/Erase Suspend instruction allows the controller to interrupt a Program or an
Erase instruction, in particular: Sector Erase and Quad Command Page Program can be
suspended and erased while that Subsector Erase, Bulk Erase, Write Non Volatile
Configuration register and Program OTP can not be suspended.
Apart form the parallelizing of the instruction code on the four pins DQ0, DQ1, DQ2 and
DQ3, the instruction functionality is exactly the same as the Program/Erase Suspend (PES)
instruction of the Extended SPI protocol, please refer to
Suspend
