Description

Data Transfer Acknowledge 1A
Data Transfer Acknowledge 0B
Data Transfer Acknowledge 0A
These bits enable or disable clearing when DMA
transfer is performed for the internal interrupt
source selected by the DTF3 to DTF0 bits in
DMACR.
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.
