Notes: 1. Modules:
CCN: Cache controller
UBC: User break controller
CPG: Clock pulse generator BSC: Bus state controller
RTC: Realtime clock
INTC: Interrupt controller
TMU: Timer unit
SCI: Serial communication interface
2. Internal buses:
L: CPU, CCN, cache, TLB connected
I:
BSC, cache, DMAC, INTC, CPG, and UDI connected
P: BSC and peripheral modules (RTC, TMU, SCI, SCIF, IrDA, A/D, D/A, DMAC,
PORT, CMT) connected
PORT, CMT) connected
3. The access size shown is for control register access (read/write). An incorrect result
will be obtained if a different size from that shown is used for access.
4. To exclude area 1 control registers from address translation by the MMU, set the first 3
bits of the logical address to 101, to locate the registers in the P2 space.
5. With 16-bit access, it is not possible to read data in two registers simultaneously.
6. With 32-bit access, it is possible to read data in the register at [accessed address + 2]
simultaneously.
