Suspend and resume
Word Program, Double Word Program, and Sector Erase operations can be suspended in
the following way:
Then the operation can be resumed in the following way:
Before resuming a suspended Erase, FCR1H/FCR1L must be read to check if the Erase is
already completed (FCR1H = FCR1L = 0x0000 if Erase is complete). Original setup of
Select Operation bits in FCR0H/L must be restored before the operation resume, otherwise
the operation is aborted and bit RESER of FER is set.
Erase suspend, program and resume
A Sector Erase operation can be suspended in order to program (Word or Double Word)
another Sector.
Example: Sector Erase of sector B0F1 of IFLASH Module.
Example: Sector Erase Suspend.
Example: Word Program of data 0x5555AAAA at address 0x045554 in IFLASH module.
Once the Program operation is finished, the Erase operation can be resumed in the
following way:
Notice that during the Program Operation in Erase suspend, bits SER and SUSP are low. A
Word or Double Word Program during Erase Suspend cannot be suspended.
