Address Name Description
DFF060 BLTCMOD Blitter modulo for source C
DFF062 BLTBMOD Blitter modulo for source B
DFF064 BLTAMOD Blitter modulo for source A
DFF066 BLTDMOD Blitter modulo for destination D


This register contains the Modulo for Blitter source (x=A,B,C) or
Dest (x=D). A modulo is a number that is automatically added to the
address at the end of each line, in order that the address then
points to the start of the next line. Each source or destination has
it's own Modulo, allowing each to be different in size, while an
identical area of each is used in the Blitter operation.
