BLTSIZV

Address Name Description DFF05C BLTSIZV Blitter vertical size (15 bit height)

Overview

Bit 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 0 H14 H13 H12 H11 H10 H9 H8 H7 H6 H5 H4 H3 H2 H1 H0

These are the blitter size regs for blits larger than the earlier
chips could accept. The original commands are retained for
compatibility. BLTSIZV should be written first, followed by BLTSIZH,
which starts the blitter. BLTSIZV need not be rewritten for
subsequent bits if the vertical size is the same.
Max size of blit 32k pixels * 32k lines.
