6.1
The H8S/2138 Group and H8S/2134 Group have an on-chip bus controller (BSC) that allows
external address space bus specifications, such as bus width and number of access states, to be set.
The bus controller also has a bus arbitration function, and controls the operation of the internal bus
masters: the CPU and data transfer controller (DTC).
6.1.1
The features of the bus controller are listed below.
Basic bus interface
Burst ROM interface
Idle cycle insertion
Bus arbitration function
2-state access or 3-state access can be selected
Program wait states can be inserted
External space can be designated as ROM interface space
1-state or 2-state burst access can be selected
An idle cycle can be inserted when an external write cycle immediately follows an external
read cycle
Includes a bus arbiter that arbitrates bus mastership between the CPU and DTC
