Comments

None.

Assumptions

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

2.6.7

FlashSuspend()

Description

This function checks if there is any high voltage operation, erase or program, in progress on

the C90FL module and if the operation can be suspended. This function suspends the

ongoing operation if it can be suspended.

Prototype

UINT32 FlashSuspend (PSSD_CONFIG pSSDConfig,

UINT8 *suspendState,

BOOL *suspendFlag);

Arguments

Table 23. Troubleshooting for CheckSum()

Returned error bits

Description

Solution

C90FL_ERROR_ALIGNMENT

This error indicates that

dest/size isn’t properly

aligned.

Check if dest and size are aligned on

double word (64-bit) boundary. Check if

source is aligned on word boundary.

C90FL_ERROR_RANGE

The area specified by

dest and size is out of

the valid C90FL address

range.

Check dest and dest+size, both should

fall in the same C90FL address ranges,

i.e. both in main array or both in shadow

row.

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.

suspendState

Indicate the suspend state

of C90FL module after the

function being called.

All return values are enumerated inTable 27.

suspendFlag

Return whether the

suspended operation, if

there is any, is suspended

by this call.

TRUE: the operation is suspended by this call;

FALSE: either no operation to be suspended or the

operation is suspended not by this call.
