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 swap of byte pairs inside 16-bit words.
2. Swap 4-bytes inside 32-bit words swap of byte foursomes inside 32-bit words.
3. Swap nibbles inside bytes
swap of high- and low- nibbles inside each byte.
Examples of swap operation in buffer:
Swap bytes operation from Start address 0 to End address N modifies data in buffer by
