9.2.7
DTCER which is comprised of registers, DTCERA to DTCERI, is a register that specifies DTC
activation interrupt sources. The correspondence between interrupt sources and DTCE bits is
shown in table 9.2. For DTCE bit setting, use bit manipulation instructions such as BSET and
BCLR for reading and writing. If all interrupts are masked, multiple activation sources can be set
at one time (only at the initial setting) by writing data after executing a dummy read on the
relevant register.
9.2.8
DTVECR sets a vector number for the software activation interrupt.

Description
DTC Activation Enable
Setting this bit to 1 specifies a relevant interrupt
source to a DTC activation source.
[Clearing conditions]
•
•
•
When the DISEL bit is 1 and the data transfer has
ended
When the specified number of transfers have
ended
These bits are not automatically cleared when the
DISEL bit is 0 and the specified number of
transfers have not ended
When 0 is written to DTCE after reading
DTCE = 1
Description
DTC Software Activation Vectors 7 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 DTVEC7
to DTVEC0 = H'10, the vector address is H'0420.
These bits can be written to only when the
SWDTE bit is 0.
