If the device receives an Erase Suspend command while in the Sector Erase state, the erase operation will
pause(afteratimedelaynotexceeding20us)andthedevicewillenterErase-SuspendedReadmode.Whilein

If a program command is issued to any inactive (not currently being erased) sector during Erase-Suspended
Readmode,thedevicewillperformtheprogramoperationandautomaticallyreturntoErase-SuspendedRead
