8.3.4
An interrupt request is issued to the CPU when the DTC finishes the specified number of data
transfers, or a data transfer for which the DISEL bit was set to 1. In the case of interrupt activation,
the interrupt set as the activation source is generated. These interrupts to the CPU are subject to
CPU mask level and interrupt controller priority level control.
In the case of activation by software, a software activated data transfer end interrupt (SWDTEND)
is generated.
When the DISEL bit is 1 and one data transfer has ended, or the specified number of transfers
have ended, after data transfer ends, the SWDTE bit is held at 1 and an SWDTEND interrupt is
generated. The interrupt handling routine should clear the SWDTE bit to 0.
When the DTC is activated by software, an SWDTEND interrupt is not generated during a data
transfer wait or during data transfer even if the SWDTE bit is set to 1.
Note: When the DTCR contains a value equal to or greater than 2, the SWDTE bit is

When register information is located in on-chip RAM, each mode requires 4 cycles for transfer
information reads, and 3 cycles for writes.
automatically cleared to 0. When the DTCR is set to 1, the SWDTE bit is again set to 1.
