Section 4 Instruction Features
Set the start and end addresses in MS and ME and then set the DMX or DMY bit to 1. The address
register contents are compared to ME. If they match ME, the start address MS is stored in the
address register. The bottom 16 bits of the address register are compared to ME. The maximum
modulo size is 64 kbytes. This is ample for accessing the X and Y data memory. Figure 4.3 shows
a block diagram of modulo addressing.
The following is an example of modulo addressing.
The above setting changes the R4 register as shown below.
