Section 2 CPU
An example of modulo addressing is given below.
As a result of the above settings, the R4 register changes as follows.
Place the data so that the upper 16 bits of the modulo start and end addresses are the same. This is
because the modulo start address overwrites only the lower 15 bits of the address register,
excluding bit 0.
Note: When addition indexing is used for DSP data addressing, the address pointer may exceed

the ME value without actually reaching it. In this case, the address pointer will not return
to the modulo start address. 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.
