Section 9 Data Transfer Controller (DTC)
9.2
DTC has the following registers.
These six registers cannot be directly accessed from the CPU. When activated, the DTC reads a set
of register information that is stored in an on-chip RAM to the corresponding DTC registers and
transfers data. After the data transfer, it writes a set of updated register information back to the
RAM.
