The DTCRB is a 16-bit register that designates the block length in block transfer mode. The block
length is 1 when the set value is H'0001, 65535 when it is H'FFFF, and 65536 when it is H'0000.
The initial value of DTCRB is undefined.
8.2.7
DTER which is comprised of six registers, DTEA to DTEE, DTEG, is a register that specifies
DTC activation interrupt sources. The correspondence between interrupt sources and DTE bits is
shown in table 8.1.

Description
DTC Activation Enable
Setting this bit to 1 specifies the corresponding
interrupt source to a DTC activation source.
[Clearing conditions]
•
•
•
These bits are not cleared when the DISEL bit is 0
and the specified number of transfers have not
ended.
[Setting condition]
1 is written to the bit to be set after a 0 has been read
from the bit
When the DISEL bit is 1 and the data transfer has
ended
When the specified number of transfers have
ended
0 is written to the bit to be cleared after 1 has
been read from the bit
