Note: Address history values are common for all buffer data manipulation dialogs.
Default address range is set according to buffer range of selected device.
Selecting option "Maintain last inserted values" causes that for the next time you open this
dialog, previously confirmed values will be reloaded as default.
Buffer / Copy block
This command is used to copy specified block of data in current buffer on new address. Target
address needn't be out from source block addresses.
Buffer / Move block
This command is used to move specified block of data in current buffer on new address.
Target address needn't be out from source block addresses. Source address block (or part)
will be filled by topical blank character.
Selecting option "Allow address history logging" activates saving of recently confirmed values.
These are saved for each device separately; count is limited to last 15 items.

Buffer / Swap block
This command swaps a high- and low- order of byte pairs, foursomes or nibbles inside bytes
depending on swap mode selected by user. Swap operation is performed on buffer block
specified by Start and End addresses. This block must start on even address and must have
an even number of bytes. If the conditions do not fulfill, the program modifies addresses itself
(start address is moved on lower even address and/or end address is moved on higher odd
address).
Following swap modes are available, user can select from:
1. Swap 2-bytes inside 16-bit words
2. Swap 4-bytes inside 32-bit words
3. Swap nibbles inside bytes
4. Mirror bits inside bytes
Example:
Swap bytes operation from Start address 0 to End address N modifies data in buffer by
following tables:
swap of byte pairs inside 16-bit words.
swap of byte foursomes inside 32-bit words.
swap of high- and low- nibbles inside each byte.
mirror bits inside each byte
