Description
Reserved
These bits are always read as 0 and cannot be
modified.
Data Transfer Acknowledge 5
These bits enable or disable clearing when DMA
transfer is performed for the internal interrupt
source selected by the DTF3 to DTF0 bits in
DMACRF of channel 5.
It the DTA5 bit is set to 1 when DTE5 = 1, the
internal interrupt source is cleared automatically by
DMA transfer. When DTE5 = 1 and DTA5 = 1, the
internal interrupt source does not issue an interrupt
request to the CPU or DTC.
It the DTA5 bit is cleared to 0 when DTE5 = 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 DTE5 = 0, the internal interrupt source issues
an interrupt request to the CPU or DTC regardless
of the DTA5 bit setting.
The state of the DTME5 bit does not affect the
above operations.
Reserved
This bit is always read as 0 and cannot be modified.
