Description
DMA Active Signal Output for Destination
This bit is used to control the output of the DMA-active
signal (DACT) for the destination corresponding to the
request source setting in the DCTG bits.
When this bit is set to "0", output of the DACT signal is
disabled and fixed high unless the level changes
because of the SACT bit setting.
When this bit is set to "1", output of the DACT signal is
valid ("L") from the next cycle after the start of the
DMAC read cycle.
However, while output of the DACT signal is enabled
when the DMA request source selection (DCTG) bits
are set for software triggering, a valid DACT signal
cannot be output when the requesting source is an on-
chip peripheral circuit (DCTG), regardless of the
setting of the DACT bit.
0: Stops output of the DMA-active signal for the
1: Selects output of the DMA-active signal for the
destination
destination during write access
