Two pages (pages 0 and 1) are provided.
The on-chip RAM is located in the address spaces shown in table 24.1.
Each page has two independent read and write ports and is connected to the internal bus (I
bus), CPU instruction fetch bus (F bus), and CPU memory access bus (M bus). (Note that the F
bus is connected only to the read ports.)
The F bus and M bus are used for access by the CPU, and the I bus is used for access by the
DMAC via the internal DMA write bus/internal DMA read bus and bus bridge.
When requests for access to the same page from different buses coincide, the access is
processed in priority order. The priority is I bus > M bus > F bus.
