Description
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 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.
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.
