static void FLASH_MassErase

(

uint32_t

Banks

)

[static]

Full erase of FLASH memory Bank.

Parameters:

Banks

Banks to be erased This parameter can be one of the following values: FLASH_BANK_1 Bank1 to be erased

Return values:

None

static HAL_StatusTypeDef FLASH_OB_DisableWRP

(

uint32_t

WriteProtectPage

)

[static]

Disable the write protection of the desired pages.

Note:

An option byte erase is done automatically in this function.

When the memory read protection level is selected (RDP level = 1), it is not possible to program or erase the flash page i if debug features are connected or boot code is executed in RAM, even if nWRPi = 1

Parameters:

WriteProtectPage

specifies the page(s) to be write unprotected. The value of this parameter depend on device used within the same series

Return values:

static HAL_StatusTypeDef FLASH_OB_ProgramData	(	uint32_t	Address,
		uint8_t	Data
	)		[static]

Programs a half word at a specified Option Byte Data address.

Note:

The function HAL_FLASH_Unlock() should be called before to unlock the FLASH interface The function HAL_FLASH_OB_Unlock() should be called before to unlock the options bytes The function HAL_FLASH_OB_Launch() should be called after to force the reload of the options bytes (system reset will occur) Programming of the OB should be performed only after an erase (otherwise PGERR occurs)

Parameters:

Address	specifies the address to be programmed. This parameter can be 0x1FFFF804 or 0x1FFFF806.
Data	specifies the data to be programmed.

Return values:
