This register controls the start bit position of the broken line pattern set to
BLP registers, for broken line drawing. The lowest 5 bits contain the bit
number of the broken line pattern. This value is decremented at each pixel
draw. Broken line drawing can be started from any position of the specified
broken line pattern by setting any number at this register.
