DCMD_F3S_STATSSR

Get the lock status of a secure silicon region

Synopsis:

#include <sys/dcmd_f3s.h>

#define DCMD_F3S_STATSSR    __DIOTF(_DCMD_F3S, F3S_STATSSR, uint32_t)

Argument	Value
`filedes`	A file descriptor that you obtained by opening the device.
`dcmd`	DCMD_F3S_STATSSR
`dev_data_ptr`	An array of type uint32_t
`n_bytes`	The number of entries in the array
`dev_info_ptr`	NULL

This command gets the lock status of a secure silicon region.

For most flash parts, the OTP area can be locked entirely. So you may pass a 1-byte data buffer to get the lock status of the entire OTP area. A value of 1 means locked, and 0 means unlocked. For example:
```
devctl(fd, DCMD_F3S_STATSSR, &stat, 1, NULL);
  
```
For some flash parts, the OTP area is divided into multiple small regions (for example 32), and each region can be locked separately. You may pass a 4-byte data buffer to get the lock stat of all 32 regions. Each bit represents the lock status of each region. For example:
```
devctl(fd, DCMD_F3S_STATSSR, &stat, 4, NULL) ;
  
```

The lock status.
