8.2.8 DTC Vector Register (DTVECR)
DTVECR enables or disables DTC activation by software, and sets a vector number for the
software activation interrupt.
Bit Bit Name Initial Value R/W Description
7 SWDTE 0 R/W DTC Software Activation Enable
Setting this bit to 1 activates DTC. Only 1 can be
written to this bit.
[Clearing conditions]
• 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 or when the specified number of transfers
have ended, this bit will not be cleared.

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 bit SWDTE is 0, these bits can be written.
