6.11.4
External bus release can be performed on completion of an external bus cycle. The RD signal and
the DRAM interface * RAS and CAS signals remain low until the end of the external bus cycle.
Therefore, when external bus release is performed, the RD, RAS, and CAS signals may change
from the low level to the high-impedance state.
Note: * The DRAM interface is not supported in the H8S/2321.
6.12
In a reset, the chip, including the bus controller, enters the reset state at that point, and any
