Section 10 Data Transfer Controller (DTC)
10.5.7
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 SWDTIE bit is set to 1.
When the DISEL bit is 1 and one data transfer has ended, or the specified number of transfers has
ended, after data transfer ends, the SWDTIF bit is set to 1 and an SWDTEND interrupt is
generated. The interrupt handling routine should clear the SWDTIF 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 and SWDTIE bit are set to 1.
