5.4.2.1.3 Guard Solid Area

Select one of three options:
Some applications require fetching the information with strictly linear address range, e.g. the memory
must be free of invalid blocks in this range. In particular, initialization of a microcontroller is possible only
if the loading code is fetching from the memory device with continiously linear address space, so the
source memory must not have invalid blocks. By default the ChipProgUSB disables guarding the
memory area. Clicking the Guard Solid Area menu line opens the pop-up dialog where you can toggle
the options:
When you select Enable in the dialog above you should specify this area by setting two parameters in
the
Start Block - the address of the first memory block that does not include invalid blocks

Solid Area setting
This default option means: "in no case do not use Spare Area for storing user's
data". Choosing this default option prevents overwriting invalid block markers in the
Spare Area by the user's data. After erasing the device Flash memory markers of the
invalid blocks will be restored in the Spare Area.
The Spare Area can be used for storing the user's data; the invalid block markers
written into the Spare Area will not be protected against overwriting by user's data.
If this option is chosen the programmer writes the data from its
device memory and when this memory is completely full the programmer begins
writing into the Spare Area. The programmer buffer displays merged memory pages,
including the Spare Area.
The Spare Area can be used for storing the user's data but the invalid block markers
written into the Spare Area against overwriting by user's data. Even if the
programmer had overwritten the invalid block markers in the Spare Area it will restore
these markers after completion of the programming operation.
