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.
• DTC enable registers A to H (DTCERA to DTCERH)
• DTC vector register (DTVECR)
