Writing into the info registers
The EXDUL module provides several writable information registers.
UserA/B are two 16-byte areas for the user to store information into a
non-volatile memory (FLASH). The registers are writable only as a whole
16-byte block.
Example: enter the character string EXDUL-581 into register UserA and UserB
