Bit 12—Single Address Enable 0 (SAE0): Specifies whether channel 0B is to be used for transfer in dual address mode
or single address mode.
This bit is invalid in full address mode.
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.
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.
Bit 11—Data Transfer Acknowledge 1B (DTA1B): Enables or disables clearing, when DMA transfer is performed, of
the internal interrupt source selected by the channel 1B data transfer factor setting.
Bit 10—Data Transfer Acknowledge 1A (DTA1A): Enables or disables clearing, when DMA transfer is performed, of
the internal interrupt source selected by the channel 1A data transfer factor setting.
Bit 9—Data Transfer Acknowledge 0B (DTA0B): Enables or disables clearing, when DMA transfer is performed, of the
internal interrupt source selected by the channel 0B data transfer factor setting.
