DTC Software Activation Enable
Setting this bit to 1 activates DTC. Only 1 can be written
to this bit.

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
H'10, the vector address is H'0420. When the SWDTE
bit is 0, these bits can be written to.
