Section 12 Data Transfer Controller (DTC)
Figure 12.1 shows a block diagram of the DTC. The DTC transfer information can be allocated to
the data area*. When the transfer information is allocated to the on-chip RAM, a 32-bit bus
connects the DTC to the on-chip RAM, enabling 32-bit/1-state reading and writing of the DTC
transfer information.
Note: * When the transfer information is stored in the on-chip RAM, the RAME bit in SYSCR
