6. Bus Controller
If a DRAM read/write cycle is followed by an access cycle for an external area other than DRAM
space when HWR and LWR are selected as the UCAS and LCAS output pins, an idle cycle (Ti) is
inserted unconditionally immediately after the DRAM access cycle. See section 6.9, Idle Cycle,
for details.
