valid for either the X or the Y address register, only; it cannot be set for both at the same time.
Therefore, DMX and DMY cannot both be set simultaneously.
The MOD register is provided to set the start and end addresses of the modulo address area. The
MOD register contains MS (Modulo Start) and ME (Modulo End). An example of the use of the
MOD register (MS and ME fields) is shown below.
The start and end addresses are specified in MS and ME, then the DMX or DMY bit is set to 1.
The address register contents are compared with ME, and if they match, start address MS is stored
in the address register. The lower 16 bits of the address register are compared with ME.
The maximum modulo size is 64 kbytes. This is sufficient to access the X and Y data memory. A
block diagram of modulo addressing is shown in figure 2.14.
An example of modulo addressing is given below.
