Interface Function prototypes
|
||
|
|
|
||
|
|
For each 28x Flash API library, the function names are of the form:
|
||
|
|
Flash<DeviceNum>_<Operation>()
|
||
|
|
|
||
|
|
Where <DeviceNum> is the device: ie 2808, 2806, 2801
|
||
|
|
<Operation> is the operation such as Erase, Program...
|
||
|
|
|
||
|
|
For portability for users who may move between the F2808, F2806 and
|
||
|
|
F2801, the following macro definitions are supplied.
|
||
|
|
|
||
|
|
Using these macro definitions, the user can use instead make a generic
|
||
|
|
call: Flash_<Operation> and the macro will map the call to the proper
|
||
|
|
device function
|
||
|
|
|
||
|
|
Note except for the toggle test function, all of the function prototypes
|
||
|
|
are compatible with F281x devices as well.
