Example of indirect addressing mode
Word program
Example: 32-bit word program of data 0xAAAAAAAA at address 0x025554
Double word program
Example: Double word program (64-bit) of data 0x55AA55AA at address 0x035558 and
data 0xAA55AA55 at address 0x03555C in IFlash module.
Double word program is always performed on the double word aligned on an even word: bit
ADD2 of FARL is ignored.
Sector erase
Example: Sector erase of sectors B0F1 and B0F0 of Bank 0 in IFlash module.
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.
