Bits 11 to 8—Data Transfer Acknowledge (DTA): These bits enable or disable clearing, when
DMA transfer is performed, of the internal interrupt source selected by the data transfer factor
setting.
When DTE = 1 and DTA = 1, the internal interrupt source selected by the data transfer factor
setting is cleared automatically by DMA transfer. When DTE = 1 and DTA = 1, the internal
interrupt source selected by the data transfer factor setting does not issue an interrupt request to the
CPU or DTC.
