Assumptions

It assumes that the Flash block is initialized using a ‘FlashInit()’ API.

2.7

User test mode functions

2.7.1

FlashArrayIntegrityCheck()

Description

This function checks the array integrity of the Flash. The user specified address sequence is

used for array integrity reads and the operation is done on the specified blocks. The MISR

values calculated by the hardware is compared to the values passed by the user, if they are

not the same, then an error code is returned.

Prototype

UINT32 FlashArrayIntegrityCheck (PSSD_CONFIG pSSDConfig,

UINT32 lowEnabledBlocks,

UINT32 midEnabledBlocks,

UINT32 highEnabledBlocks,

UINT8 addrSeq,

MISR misrValue,

void (*CallBack)(void));

Arguments

Table 42. 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 2.3 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.
