Typedefs
typedef struct IotEfuseDescriptor *	IotEfuseHandle_t
	IotEfuseHandle_t is the handle type returned by calling iot_efuse_open(). This is initialized in open and returned to caller. The caller must pass this pointer to the rest of APIs.

Functions
IotEfuseHandle_t	iot_efuse_open (void)
	iot_efuse_open is used to Initialize things needed to access efuse. More...
int32_t	iot_efuse_close (IotEfuseHandle_t const pxEfuseHandle)
	iot_efuse_close is used to de Initialize things needed to disable efuse access. More...
int32_t	iot_efuse_read_32bit_word (IotEfuseHandle_t const pxEfuseHandle, uint32_t ulIndex, uint32_t *ulValue)
	Read 32-bit efuse word from specified index. More...
int32_t	iot_efuse_write_32bit_word (IotEfuseHandle_t const pxEfuseHandle, uint32_t ulIndex, uint32_t ulValue)
	Write 32-bit value to the 32-bit efuse word at specified index. More...
int32_t	iot_efuse_read_16bit_word (IotEfuseHandle_t const pxEfuseHandle, uint32_t ulIndex, uint16_t *ulValue)
	Read 16-bit efuse word from specified index. More...
int32_t	iot_efuse_write_16bit_word (IotEfuseHandle_t const pxEfuseHandle, uint32_t ulIndex, uint16_t value)
	Write 16-bit value to the 16-bit efuse word at specified index. More...
