Table 31. Arguments for GetLock()

Argument

Description

Range

pSSDConfig

Pointer to the SSD

Configuration Structure.

The values in this structure are chip-dependent.

Please refer to Section 2.3 for more details.

blkLockIndicator

Indicating the address space

and the block locking level,

which determines the address

space block locking register

to be checked.

Refer to Table 34 for valid values for this

parameter.

blkLockEnabled

Indicate whether the address

space block locking register is

enabled for register writes

TRUE – The address space block locking register

is enabled for register writes.

FALSE – The address space block locking

blkLockState

Returns the blocks’ locking

status of indicated locking

level in the given address

space

Bit mapped value indicating the locking status of

the specified locking level and address space.

1: The block is locked from program/erase.

0: The block is ready for program/erase
