AT91SAM9XE128/256/512 Preliminary
In-Application Programming (IAP) Feature
The IAP feature is a function located in ROM that can be called by any software application.
When called, this function sends the desired FLASH command to the EEFC and waits for the
FLASH to be ready (looping while the FRDY bit is not set in the MC_FSR register).
Since this function is executed from ROM, this allows FLASH programming (like sector write) to
be done by code running in FLASH.
The IAP function entry point is retrieved by reading the SWI vector in ROM (0x100008).
This function takes one argument in parameter: the command to be sent to the EEFC.
This function returns the value of the MC_FSR register.
IAP software code example:
(unsigned int) (*IAP_Function)(unsigned long);
void main (void)
{
/* Initialize the function pointer (retrieve function address from SWI
vector) */
/* Send your data to the sector */
/* build the command to send to EFC */
/* Call the IAP function with appropriate command */
}
unsigned long FlashSectorNum = 200;
unsigned long flash_cmd = 0;
unsigned long flash_status = 0;
IAP_Function = ((unsigned long) (*)(unsigned long)) 0x100008;
flash_cmd =
flash_status = IAP_Function (flash_cmd);
(0x5A << 24) | (FlashSectorNum << 8) | AT91C_MC_FCMD_EWP;
