Flash
Description:
This function will program a sequence of words into the on-chip flash. Each word in a page of
flash can only be programmed one time between an erase of that page; programming a word
multiple times will result in an unpredictable value in that word of flash.
Since the flash is programmed one word at a time, the starting address and byte count must
both be multiples of four. It is up to the caller to verify the programmed contents, if such
verification is required.
This function will not return until the data has been programmed.
Returns:
Returns 0 on success, or -1 if a programming error is encountered.
8.2.1.7 ROM_FlashProtectGet
Gets the protection setting for a block of flash.
Prototype:
tFlashProtection
ROM_FlashProtectGet(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_FlashProtectGet is a function pointer located at ROM_FLASHTABLE[4].
Parameters:
ui32Address is the start address of the flash block to be queried.
Description:
This function will get the current protection for the specified 2 kB block of flash. Each block can
be read/write, read-only, or execute-only. Read/write blocks can be read, executed, erased,
and programmed. Read-only blocks can be read and executed. Execute-only blocks can only
be executed; processor and debugger data reads are not allowed.
Returns:
Returns the protection setting for this block. See ROM_FlashProtectSet() for possible values.
8.2.1.8 ROM_FlashProtectSave
Saves the flash protection settings.
Prototype:
int32_t
ROM_FlashProtectSave(void)
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_FlashProtectSave is a function pointer located at ROM_FLASHTABLE[6].
