Function Documentation

void FLASH_Erase_Sector	(	uint32_t	Sector,
		uint8_t	VoltageRange
	)

Erase the specified FLASH memory sector.

Parameters:

Sector

FLASH sector to erase The value of this parameter depend on device used within the same series

VoltageRange

The device voltage range which defines the erase parallelism. This parameter can be one of the following values: FLASH_VOLTAGE_RANGE_1: when the device voltage range is 1.8V to 2.1V, the operation will be done by byte (8-bit) FLASH_VOLTAGE_RANGE_2: when the device voltage range is 2.1V to 2.7V, the operation will be done by half word (16-bit) FLASH_VOLTAGE_RANGE_3: when the device voltage range is 2.7V to 3.6V, the operation will be done by word (32-bit) FLASH_VOLTAGE_RANGE_4: when the device voltage range is 2.7V to 3.6V + External Vpp, the operation will be done by double word (64-bit)

Return values:

None
