7.2
The DTC has the following registers.
These six registers cannot be directly accessed from the CPU. When a DTC activation interrupt
source occurs, the DTC reads a set of register information that is stored in 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 on-chip RAM.
7.2.1
MRA selects the DTC operating mode.
DTC mode register A (MRA)
