| |
Program raw fuse value.
This function program specified value into fuse area, without redundancy protection bits.
- Parameters
-
| index | Fuse index |

index, |
|
|
uint32_t * |
data |
|
) |
| |
Load fuse value by software.
This function manually triggers fuse reading operation to specified index, and store fuse value in user buffer.
