• The bus is transferred at a break between bus cycles. However, if a bus cycle is executed in
• If the CPU is in sleep mode, it transfers the bus immediately.
DMAC: The DMAC sends the bus arbiter a request for the bus when an activation request is
generated.
In the case of a USB request in short address mode or normal mode, and in cycle steal mode, the
DMAC releases the bus after a single transfer.
In block transfer mode, it releases the bus after transfer of one block, and in burst mode, after
completion of the transfer.
6.10.3
External bus release can be performed on completion of an external bus cycle in the H8S/2218
Group. The CS signal remains low until the end of the external bus cycle. Therefore, when
external bus release is performed, the CS signal may change from the low level to the high-
impedance state.
6.11
In a power-on reset, this LSI, including the bus controller, enters the reset state at that point, and an
executing bus cycle is discontinued.
In a manual reset*, the bus controller's registers and internal state are maintained, and an executing
external bus cycle is completed. In this case, WAIT input is ignored and write data is not
guaranteed.
Note: * Supported only by the H8S/2218 Group.

discrete operations, as in the case of a longword-size access, the bus is not transferred between
the operations.
