2. Registers within the DTC cannot be read or written to directly.
3. Allocated to on-chip RAM addresses H'EC00 to H'EFFF as register information.
4. The H8S/2144 Group and H8S/2147N do not include an on-chip DTC, and therefore the
Register Configuration
When the DTC is used, do not clear the RAME bit in SYSCR to 0.
They cannot be located in external memory space.
DTCER and DTVECR register addresses should not be accessed by the CPU.
