Section 10 Data Transfer Controller (DTC)
10.2.9
DTCVBR is a 32-bit register that specifies the base address for vector table address calculation.
Bits 31 to 24 and 11 to 0 are fixed to 0 and cannot be modified.
The initial value of DTCVBR is H'00000000.
10.2.10 DTC Control Register (DTCCR)
DTCCR enables or disables DTC activation by software.

Description
DTC Software Activation Enable
Setting this bit to 1 activates the DTC. The value
set in DTVECR is used as the vector number. This
bit is cleared to 0 when data transfer ends.
Set the vector number to DTVECR, set this bit to
1, and then confirm the value in DTVECR again. If
the value in DTVECR does not match the vector
number that has been set, this means that an
interrupt has occurred before this bit was set to 1.
In this case, set the vector number in DTVECR
again and then set this bit to 1.
Only 1 can be written to this bit.
[Clearing condition]

DTC Software Activation Interrupt Enable
Setting this bit to 1 enables a software activated
data transfer end interrupt request sent to the
CPU.
When the data transfer performed by software
activating the DTC has ended
