Figure 8-1 shows a block diagram of the DTC.
The DTC’s register information is stored in the on-chip RAM*. A 32-bit bus connects the DTC to the on-chip RAM (1
kbyte), enabling 32-bit/1-state reading and writing of the DTC register information and hence helping to increase
processing speed.
Note: * When the DTC is used, the RAME bit in SYSCR must be set to 1.
