Address
MOV #0x1100, W0
MOV W0, XMODSRT ;set modulo start address
MOV #0x1163, W0
MOV W0, MODEND ;set modulo end address
MOV #0x8001, W0
MOV W0, MODCON ;enable W1, X AGU for modulo
MOV #0x0000, W0 ;W0 holds buffer fill value
MOV #0x1110, W1 ;point W1 to buffer
DO AGAIN, #0x31 ;fill the 50 buffer locations
MOV W0, [W1++] ;fill the next location
AGAIN: INC W0, W0 ;increment the fill value
