Bit 14—Full Address Enable 0 (FAE0): Specifies whether channel 0 is to be used in short
address mode or full address mode.
In full address mode, channels 0A and 0B are used together as a single channel.

Bits 13 and 12—Reserved: Can be read or written to. Only 0 should be written to these bits.
Bits 11 and 9—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.
When DTE = 1 and DTA = 0, the internal interrupt source selected by the data transfer factor
setting 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 selected by the data transfer factor setting issues an
interrupt request to the CPU or DTC regardless of the DTA bit setting.
The state of the DTME bit does not affect the above operations.
Bit 11—Data Transfer Acknowledge 1 (DTA1): Enables or disables clearing, when DMA
transfer is performed, of the internal interrupt source selected by the channel 1 data transfer factor
setting.
