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.

shadowFlag

Indicate either the main array

or the shadow row to be

erased.

TRUE: the shadow row is erased. The

lowEnabledBlocks, midEnabledBlocks and

highEnabledBlocks is ignored;

FALSE: The main array is erased. Which blocks are

erased in low, mid and high address spaces are

specified by lowEnabledBlocks, midEnabledBlocks and

highEnabledBlocks respectively.

lowEnabledBlocks

To select the array blocks in

low address space for

erasing.

Bit-mapped value. Select the block in the low address

space to be erased by setting 1 to the appropriate bit of

lowEnabledBlocks. If there is not any block to be erased

in the low address space, lowEnabledBlocks must be set

to 0.

midEnabledBlocks

To select the array blocks in

mid address space for

erasing.

Bit-mapped value. Select the block in the middle

address space to be erased by setting 1 to the

appropriate bit of midEnabledBlocks. If there is not any

block to be erased in the middle address space,

midEnabledBlocks must be set to 0.

highEnabledBlocks

To select the array blocks in

high address space for

erasing.

Bit-mapped value. Select the block in the high address

space to be erased by setting 1 to the appropriate bit of

highEnabledBlocks. If there is not any block to be erased

in the high address space, highEnabledBlocks must be

set to 0.

CallBack

Address of void call back

function pointer.

Any addressable void function address. To disable it,

use NULL_CALLBACK macro.
