Functions of Index Register and Data Memory Row Address Pointer

When a data memory manipulation instruction is executed with the index enable flag (IXE) set to 1, the

index register ORs the data memory bank/address specified by the instruction and the contents of the index

operation result (in other words, the real address).

When a general-purpose register indirect transfer instruction (MOV @r, m and MOV m, @r) is executed

with the memory pointer enable flag set to 1, the data memory row address pointer executes the instruction,

regarding the indirect address bank specified by the general-purpose register and row address as being the

value of the data memory row address pointer.

Table 8-2 shows the modification of data memory and the indirect address by the index register and data

memory row address pointer.

All data memories are subject to modification by the index register and data memory row address pointer.

The following instructions are not subject to modification by the index register.
