Setting this bit to 1 activates DTC. Only 1 can always be
written to this bit. 0 can be written to after reading 1
from this bit.

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
H'10, the vector address is H'0420. When the SWDTE
bit is 0, these bits can be written to.
Description
DTC Software Activation Enable
When the DISEL bit is 0 and the specified number of
transfers have not ended.
When 0 is written to the DISEL bit after a software-
activated data transfer end interrupt (SWDTEND)
request has been sent to the CPU.
When the DISEL bit is 1 and data transfer has
ended
When the specified number of transfers have ended.
During data transfer activated by software
