8.2 Register Descriptions
DTC has the following registers.
DTC mode register A (MRA)
DTC mode register B (MRB)
DTC source address register (SAR)
DTC destination address register (DAR)
DTC transfer count register A (CRA)
DTC transfer count register B (CRB)
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.
