DMA Interrupt Setting Register (DMINT)
DARIE Bit (Destination Address Extended Repeat Area Overflow Interrupt Enable)
When an extended repeat area overflow on the destination address occurs while this bit is set to 1, the DTE bit in
DMCNT is cleared to 0. At the same time, the ESIF flag in DMSTS is set to 1 to indicate that an interrupt by an extended
repeat area overflow on the destination address is requested.
When block transfer mode is used with the extended repeat area function, an interrupt is requested after completion of a
1-block size transfer. When setting 1 in the DTE bit in DMACm.DMCNT of the channel for which a transfer has been
stopped, the transfer is resumed from the state when the transfer is stopped.
When the extended repeat area is not specified for the destination address, this bit is ignored.
SARIE Bit (Source Address Extended Repeat Area Overflow Interrupt Enable)
When an extended repeat area overflow on the source address occurs while this bit is set to 1, the DTE bit in DMCNT is
cleared to 0. At the same time, the ESIF flag in DMSTS is set to 1 to indicate that an interrupt by an extended repeat area
overflow on the source address is requested.
When block transfer mode is used with the extended repeat area function, an interrupt is requested after completion of a
1-block size transfer. When setting 1 in the DTE bit in DMACm.DMCNT of the channel for which a transfer has been
stopped, the transfer is resumed from the state when the transfer is stopped.
When the extended repeat area is not specified for the source address, this bit is ignored.
