Single Address Enable 0
Description
Specifies whether channel 1 is to be used for
transfer in dual address mode or single address
mode.

These bits enable or disable clearing when DMA
transfer is performed for the internal interrupt source
selected by the DTF3 to DTF0 bits in DMACRS.
If the DTA bit is set to 1 when DTE = 1, the internal
interrupt source is cleared automatically by DMA
transfer. When DTE = 1 and DTA = 1, the internal
interrupt source does not issue an interrupt request
to the CPU or DTC.
If the DTA bit is cleared to 0 when DTE = 1, the
internal interrupt source is not cleared when a
transfer is performed, and can issue an interrupt
request to the CPU or DTC in parallel. In this case,
the interrupt source should be cleared by the CPU
or DTC transfer.
When DTE = 0, the internal interrupt source issues
an interrupt request to the CPU or DTC regardless
of the DTA bit setting.
