For these generic defines the flash sectoring needs to be defined For details please refer to the chapter Flash sectoring If you intend to use 2 flash chips both 16bit wide that combined define a 32bit flash module please use the following macro to enable both the correct sector ing of the flash module and correct programming algorithm Macro Explanation FLASH_32BIT Set to 1 enables the 32bit mode algorithm 8 5 3 Flash sectoring If a flash chip is selected the flash driver knows the sectoring of the chip Only if a generic define for the chip selection is used the sectoring needs to be de fined This is done by defining the Sector addresses for all relevant sectors of the chip e g as follows in case of a 256 Kbyte device with 4 sectors define FLASH_SA0 0x000000 16K Boot block define FLASH_SA1 0x004000 8K Parameter block define FLASH_SA2 0x006000 8K Parameter block define FLASH_SA3 0x008000 240 Main memory block define FLASH_SA4 0x040000 End 8 5 4 Additional options The following table shows the additional configuration options available for the NOR flash driver Macro Explanation FLASH_8BIT Selects the 8 bit mode Set to 1 if the driver should work in 8 bit mode The default value depends on the selected flash Note that not each flash sup ports both modes FLASH_16BIT Selects the 16 bit mode Set to 1 if the driver should work in 16 bit mode The defau
