OPERATION
3-9
The BUFC signal is used when the address-data bus has an external buffer. It controls the buffer direction.
This signal can be used to facilitate buffer control.
Figure 3.6 shows an example of connecting the external peripheral/memory to the MB89630 series of
micro controllers. In this circuit, the external bus is used after enabling the operation of the HAK pin by the
external ROM. When using the hold function, the pull-up resistor must be attached externally to the HAK
pin.
At access to internal ROM, A15 to A08, AD7 to AD0, and ALE are output but WR and RD are not output.
