8.2.1 Function Documentation
8.2.1.1 ROM_FlashErase
Erases a block of flash.
Prototype:
int32_t
ROM_FlashErase(uint32_t ui32Address)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_FLASHTABLE is an array of pointers located at ROM_APITABLE[7].
ROM_FlashErase is a function pointer located at ROM_FLASHTABLE[3].
Parameters:
ui32Address is the start address of the flash block to be erased.
Description:
This function will erase a 1 kB block of the on-chip flash. After erasing, the block is filled with
0xFF bytes. Read-only and execute-only blocks cannot be erased.
This function will not return until the block has been erased.
Returns:
Returns 0 on success, or -1 if an invalid block address was specified or the block is write-
protected.
8.2.1.2 ROM_FlashIntClear
Clears flash controller interrupt sources.
Prototype:
void
ROM_FlashIntClear(uint32_t ui32IntFlags)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_FLASHTABLE is an array of pointers located at ROM_APITABLE[7].
ROM_FlashIntClear is a function pointer located at ROM_FLASHTABLE[13].
Parameters:
ui32IntFlags is the bit mask of the interrupt sources to be cleared. Can be any of the
FLASH_INT_PROGRAM or FLASH_INT_AMISC values.
Description:
The specified flash controller interrupt sources are cleared, so that they no longer assert. This
must be done in the interrupt handler to keep it from being called again immediately upon exit.
