Section 3 DSP Operating Unit
An example of the use of modulo addressing is shown below.
The start and end addresses are specified in MS and ME, then the DMX or DMY bit is set to 1.
When the X or Y data transfer instruction specified by the DMX or DMY is executed, the address
register contents before updating are compared with ME
stored in the address register as the value after updating.
When the addressing type of the X/Y data transfer instruction is no-update, the X/Y data transfer
instruction is not returned to MS even if they match ME.
When the addressing type of the X/Y data transfer instruction is addition index register addressing,
the address pointed way not match the address pointer ME and exceed it. In this case, the address
pointer value does not become the modulo start address.
The maximum modulo size is 64 kbytes. This is sufficient to access the X and Y data memory.

Not only with modulo addressing, but when X and Y data addressing is used, bit 0 is
ignored. 0 must always be written to bit 0 of the address pointer, index register, MS,
and ME.
