Always clear the Status Register prior to resuming erase operations. It avoids Status Register ambiguity when issuing
commands during Erase Suspend. If a command sequence error occurs during an erase-suspend state, the Status Register
contains the command sequence error status (SR[7,5,4] set). When the erase operation resumes and finishes, possible
errors during the erase operation cannot be detected via the Status Register because it contains the previous error status
BEFP mode is only valid in array.

Register
When non-array reads are performed in asynchronous page mode, only the first data is
valid and all subsequent data are undefined. When a non-array read operation occurs
as synchronous burst mode, the same word of data requested will be output on
successive clock edges until the burst length requirements are satisfied.
Status Register (SR)
The Status Register provides the ready/busy information of the device, as well as the
error information about the program, erase, VPP and block-locked operations. please
