8-bit immediate constant value
Add the 8-bit unsigned constant to the XARn register pointed to by ARP:
XAR(ARP) = XAR(ARP) + 0:8bit;
The 3-bit ARP points to the current valid Auxiliary Register, XAR0 to XAR7.
This pointer determines which Auxiliary register is modified by the operation.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once
