API specification

3.1

General overview

The C90FL(2) SSD has APIs to handle the erase, program, erase verify and program verify

operations on the Flash. Apart from these, it also provides the feature for locking specific

blocks and calculating check sum.

General type definitions

3.3

Configuration parameters and macros

The configuration parameters, which are used for SSD operations, are explained in this

section. The configuration parameters are handled as a structure. The user should correctly

initialize the fields including c90flRegBase, mainArrayBase, shadowRowBase,

shadowRowSize, pageSize and BDMEnable before passing the structure to the SSD

functions. The pointer to CallBack has to be initialized either to a null pointer or a valid

function pointer.
