Arguments

Table 39. Arguments for FlashArrayIntegrityCheck()

Argument

Description

Range

pSSDConfig

Pointer to the SSD

Configuration Structure.

The values in this structure are chip-dependent.

Please refer to Section 3.3 for more details.

lowEnabledBlocks

To select the array

blocks in low address

space for erasing.

Bit-mapped value. Select the block in the low

address space whose array integrity is to be

evaluated by setting 1 to the appropriate bit of

lowEnabledBlocks. If there is not any block to be

evaluated 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 whose array integrity is to be

evaluated by setting 1 to the appropriate bit of

midEnabledBlocks. If there is not any block to be

evaluated 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 whose array integrity is to be

evaluated by setting 1 to the appropriate bit of

highEnabledBlocks. If there is not any block to be

evaluated in the high address space,

highEnabledBlocks must be set to 0.

addrSeq

To determine the

address sequence to be

used during array

integrity checks.

The default sequence (addrSeq = 0) is meant to

replicate sequences normal “user” code follows,

and thoroughly check the read propagation paths.

This sequence is proprietary.

The alternative sequence (addrSeq = 1) is just

logically sequential.

It should be noted that the time to run a sequential

sequence is significantly shorter than the time to

run the proprietary sequence.

misrValue_Bk0

A structure variable

containing the MISR

values for Bank 0

calculated by the user by

using an off-line MISR

calculator.

The individual MISR words can range from

0x00000000 - 0xFFFFFFFF

misrValue_Bk1

A structure variable

containing the MISR

values for Bank 1

calculated by the user by

using an off-line MISR

calculator.

The individual MISR words can range from

0x00000000 - 0xFFFFFFFF

CallBack

Address of void call back

function pointer.

Any addressable void function address. To disable

it use NULL_CALLBACK macro.
