6.3
Figure 6.4 shows the internal bus configuration of this LSI. The internal bus of this LSI consists of
the following three types.
• Internal system bus
• Internal peripheral bus
• External access cycle
A bus that connects the CPU, DTC, DMAC, on-chip RAM, on-chip ROM, internal peripheral
bus, and external access bus.
A bus that accesses registers in the bus controller, interrupt controller, and DMAC, and
registers of peripheral modules such as SCI and timer.
A bus that accesses external devices via the external bus interface.
