The value to be added to the address register depends on addressing
instructions.
For example, (+2 or R8[Ix] or +0) means that
+2: if instruction is increment
R8[Ix]: if instruction is add-index-register
+0: if instruction is not-update

function modulo ( AddrReg, Index ) {
if ( AddrReg[15:1]==ME[15:1] ) AddrReg[15:1]==MS[15:1];
else AddrReg=Index;
return AddrReg;
}
X and Y Data Transfer Instructions (MOVX.W and MOVY.W): This type of instruction uses
the XDB and the YDB to access X and Y data memories (they cannot access other memory
spaces). These two buses are separate from the instruction bus, therefore, there is no access
conflict between data memory access and instruction memory access.
Figure 3.22 shows load/store control for X and Y data transfer instructions. All memory accesses
are word mode accesses.
