Note: 2. Writing/Reading operation for VRAM during non cycle steal access is performed during overlapping
MCS
and [
LWR (+HWR) or RD].
Limits of
MCS, LWR (+HWR) and RD are prescribed by the input signal of last change to "L" in starting
access, and by the input signal of first change to "H" in ending access.
