HAL_EFUSE_Read()

int32_t HAL_EFUSE_Read	(	uint16_t	bit_offset,
		uint8_t *	data,
		int	size
	)

Read data to efuse starting from bit_offset.

Parameters

bit_offset	bit_offset in efuse, must be 32bits aligned, bank0: 0~255, bank1: 256~511
data	point to buffer to save read data
size	data size in byte, must be multiple of 4bytes and read data cannot cross bank boundary

Return values

size	successfully read
