Section 6 Bus Controller (BSC)
6.4.2
Bus Specifications
The external address space bus specifications consist of five elements: bus width, number of
access states, number of program wait states, read strobe timing, and chip select (CS) assertion
period extension states. The bus width and number of access states for on-chip memory and
internal I/O registers are fixed, and are not affected by the bus controller.
Bus Width: A bus width of 8 or 16 bits can be selected with ABWCR. An area for which an 8-bit
bus is selected functions as an 8-bit access space, and an area for which a 16-bit bus is selected
functions as a 16-bit access space. If all areas are designated as 8-bit access space, 8-bit bus mode
is set; if any area is designated as 16-bit access space, 16-bit bus mode is set.
Number of Access States: Two or three access states can be selected with ASTCR. An area for
which 2-state access is selected functions as a 2-state access space, and an area for which 3-state
access is selected functions as a 3-state access space. With the DRAM or synchronous DRAM
interface and burst ROM interface, the number of access states may be determined without regard
to the setting of ASTCR.
When 2-state access space is designated, wait insertion is disabled. When 3-state access space is
designated, it is possible to insert program waits by means of the WTCRA and WTCRB, and
external waits by means of the WAIT pin.
Note: The synchronous DRAM interface is not supported in the H8S/2678 Group.
Number of Program Wait States: When 3-state access space is designated by ASTCR, the
number of program wait states to be inserted automatically is selected with WTCRA and WTCRB.
From 0 to 7 program wait states can be selected. Table 6.2 shows the bus specifications (bus
width, and number of access states and program wait states) for each basic bus interface area.
