DTC Vector Register (DTVECR)
DTVECR enables or disables DTC activation by software, and sets a vector number for the
software activation interrupt.

DTC Software Activation Enable
Setting this bit to 1 activates DTC. Only 1 can be written
to this bit.
[Clearing conditions]
1. When the DISEL bit is 0 and the specified number of
transfers have not ended
2. When 0 is written to the DISEL bit after a software-
activated data transfer end interrupt (SWDTEND)
request has been sent to the CPU.
This bit will not be cleared when the DISEL bit is 1 and
data transfer has ended or when the specified number
of transfers have ended.

DTC Software Activation Vectors 6 to 0
These bits specify a vector number for DTC software
activation.
The vector address is expressed as H'0400 + (vector
number
×
2). For example, when DTVEC6 to DTVEC0 =
H'10, the vector address is H'0420. When the SWDTE
bit is 0, these bits can be written to.
