8.1.2
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 DTC register
information.
Note: * When the DTC is used, the RAME bit in SYSCR must be set to 1.
