When the check box Automatic file format recognition is
unchecked program allows user to manually select wished file
format from list of available file formats on panel Selected file
format. When Binary file format is selected, there can be
specified Buffer start value. Buffer start value is buffer address
from which data read from file will be written to buffer.
If the checkbox Swap bytes is displayed, the user can activate
function of swapping bytes within 16bit words (or 2-byte words)
during reading of file. This feature is useful especially when
loading files with Motorola representation of byte order in file
(big endian). Standard load file is using little endian byte order.
Note: Big-endian and little-endian are terms that describe the
order in which a sequence of bytes are stored in computer
memory. Big-endian is an order in which the "big end" (most
significant value in the sequence) is stored first (at the lowest
storage address). Little-endian is an order in which the "little
end" (least significant value in the sequence) is stored first. For
example, in a big-endian computer, the two bytes required for
the hexadecimal number 4F52 would be stored as 4F52H in
storage address 1000H as: 4FH is stored at storage address
1000H, and 52H will be at address 1001H. In a little-endian
system, it would be stored as 524FH (52H at address 1000H,
and 4FH at address 1001H).
Number 4F52H is stored in memory:
Address Big endian
1000H
1001H

File / Save
Saves data in the buffer, which has been created, modified, or
read from a device onto a specified disk. The file format of
saved file can be chosen from supported formats list box.
There can be also entered the Buffer start and Buffer end
addresses which exactly specify part of buffer to save to file.
Supported file formats now are binary, MOTOROLA, MOS
Technology, Tektronix, Intel (extended) HEX, ASCII space,
JEDEC and POF.
If the checkbox Swap bytes is displayed, the user can activate
