In group When current file is modified by another process
can be set mode of reloading of actually loaded (current) file.
There are three choices:
1. Prompt before reloading file
2. Reload automatically
3. Ignore change scanning of current file
Load file format allows to set mode of file format recognition
for loading files. When automatic file format is selected,
program analyses format of loading file and test file for each of
supported formats that are available in program. If file format
matches one of supported formats, the file is read to buffer in
detected format.
Manual file format allows user to select explicitly wished file
format from list of supported file formats. File may be loaded
no completely or incorrectly, if file format does not match to
user selected format.
Hex file options
This page contains several options for loading control by any
of HEX formats.
The first option sets erasing buffer (with desired value)
automatically before the loading by any of HEX formats.
The second option sets a negative offset, which is used for
data addresses modification by loading from any HEX file so,
that data can be written to existing buffer addresses. Manual or
Automatic negative offset mode can be set. We recommend
automatic set of negative offset in special cases only. This
option contain a heuristic analyse, which can treat some data
in file incorrectly. There are especially critical files, which
contain a fragmented addresses range and which exceeds a
size of selected device - some block can be ignored. Automatic
set of negative offset can be disabled by select of any special
devices. No address range in files associated with special
devices can be moved and no block can be removed from the
file when reading the file. For special devices following
negative offset options are available: Yes (negative offset is
turned on) and No (negative offset is not used).
Example:
A file contents data by Motorola S - format. A data block
started at address FFFF0H. It is a S2 format with length of
address array of 3 bytes. For all data reading you can set a
value of negative offset to FFFF0H. It means, that the offset
will be subtracted from current real addresses and so data will
be written from buffer address 0.
Warning: The value of negative offset is subtracted from real
address and therefore a result of subtraction can be negative
number. Because take care of correct setting of this value.
