The Program/Erase Resume command must be written to resume the program or sector/block erase operation
after a Program/Erase Suspend command. The Program/Erase command will be accepted by the device only if
the SUS2/SUS1 bit equal to 1 and the WIP bit equal to 0. After issued the SUS2/SUS1 bit in the status register
will be cleared from 1 to 0 immediately, the WIP bit will be set from 0 to 1 within 200ns and the Sector or
Block will complete the erase operation or the page will complete the program operation. The Program/Erase
Resume command will be ignored unless a Program/Erase Suspend is active. The command sequence is show in
