Write operation examples
In the following, examples for each kind of Flash write operation are presented.
Word program
Example: 32-bit Word Program of data 0xAAAAAAAA at address 0x0C5554 in XFLASH
Module.
Double word program
Example: Double Word Program (64-bit) of data 0x55AA55AA at address 0x095558 and
data 0xAA55AA55 at address 0x09555C in IFLASH Module.
Double Word Program is always performed on the Double Word aligned on a even Word: bit
ADD2 of FARL is ignored.
Sector erase
Example: Sector Erase of sectors B3F1 and B3F0 of Bank 3 in XFLASH 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.
FCR0H|= 0x2000; /*Set WPG in FCR0H*/
FARL = 0x5554; /*Load Add in FARL*/
FARH = 0x000C; /*Load Add in FARH*/
FDR0L = 0xAAAA; /*Load Data in FDR0L*/
FDR0H = 0xAAAA; /*Load Data in FDR0H*/
FCR0H|= 0x8000; /*Operation start*/
FCR0H|= 0x1080; /*Set DWPG, SMOD*/
FARL

FDR0L = 0x55AA; /*Load Data in FDR0L*/
FDR0H = 0x55AA; /*Load Data in FDR0H*/
FDR1L = 0xAA55; /*Load Data in FDR1L*/
FDR1H = 0xAA55; /*Load Data in FDR1H*/
FCR0H|= 0x8000; /*Operation start*/
FCR0H|= 0x0800; /*Set SER in FCR0H*/
FCR1H|= 0x0003; /*Set B3F1, B3F0*/
FCR0H|= 0x8000; /*Operation start*/
FCR0H|= 0x4000; /*Set SUSP in FCR0H*/
FCR0H|= 0x0800; /*Set SER in FCR0H*/
FCR0H|= 0x8000; /*Operation resume*/
= 0x5558; /*Load Add in FARL*/
= 0x0009; /*Load Add in FARH*/
