Operation
Operations Allowed / Disallowed During Device States
Program/Erase Resume
After a Program/Erase suspend instruction, a Program/Erase Resume instruction is
required to continue performing the suspended Program or Erase sequence.
Program/Erase Resume instruction is ignored if the device is not in a Program/Erase
Suspended status. The WIP bit of the Status Register and Program/Erase controller bit (Not
WIP) of the Flag Status Register both switch to the busy state (1 and 0 respectively) after
Program/Erase Resume instruction until the Program or Erase sequence is completed.
In this case the next Program/Erase Resume Instruction resumes the more recent
suspended modify cycles, another Program/Erase Resume Instruction is need to resume
also the former one.
Read Status Register (RDSR)
The Read Status Register (RDSR) instruction allows the Status Register to be read. The
Status Register may be read at any time, even while a Program, Erase or Write Status
Register cycle is in progress. When one of these cycles is in progress, it is recommended to
check the Write In Progress (WIP) bit (or the Program/Erase controller bit of the Flag Status
