Description
Single Address Enable 0
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.
0: Dual address mode
1: Single address mode
Data Transfer Acknowledge 1B
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.
