Resets and the Bus Controller
In a power-on reset, the H8S/2357 Group, 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. Also, since the DMAC is initialized by a manual reset*, DACK and
TEND output is disabled and these pins become I/O ports controlled by DDR and DR.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
