1. The Read operation is accepted but the data output is not guaranetted until the program or erase has completed.
Note:
The device can be in only one state at a time, such as Standby, Program, Erase, and so on.
Device states are shown in Table 19.: Operations Allowed / Disallowed During Device
States.
9.1.21
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.
