Section 6 Bus Controller
6.4
6.4.1
A different bus control signal timing applies when dynamic RAM or pseudo-static RAM is
connected to area 3. For details see section 7, Refresh Controller.
6.4.2
ABWCR, ASTCR, and WCER Write Timing
Data written to ABWCR, ASTCR, or WCER takes effect starting from the next bus cycle. Figure
6.20 shows the timing when an instruction fetched from area 0 changes area 0 from three-state
access to two-state access.
