Description
Data Transfer Acknowledge 0
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 of channel 0.
It the DTA0 bit is set to 1 when DTE0 = 1, the
internal interrupt source is cleared automatically
by DMA transfer. When DTE0 = 1 and DTA0 = 1,
the internal interrupt source does not issue an
interrupt request to the CPU or DTC.
It the DTA0 bit is cleared to 0 when DTE0 = 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 DTE0 = 0, the internal interrupt source
issues an interrupt request to the CPU or DTC
regardless of the DTA0 bit setting.
The state of the DTME0 bit does not affect the
above operations.
Reserved
This bit can be read from or written to. However,
the write value should always be 0.
