Description
DMA Active
Controls the DMA operation. When this bit is set to 1,
this indicates that an DMA operation is in progress.
When auto request mode is specified (by bits MDS1
and MDS0), transfer processing begins when this bit is
set to 1. With external requests, transfer processing
begins when a transfer request is issued after this bit
has been set to 1. When this bit is cleared to 0 during
an DMA operation, transfer is halted. If this bit is
cleared to 0 during an DMA operation in block transfer
mode, transfer processing is continued for the currently
executing one-block transfer, and the bit is cleared on
completion of the currently executing one-block
transfer.
If an external source that ends (aborts) transfer occurs,
this bit is automatically cleared to 0 and transfer is
terminated. Do not change the operating mode, transfer
method, or other parameters while this bit is set to 1.
0: Data transfer disabled on corresponding channel
[Clearing conditions]
1: Data transfer enabled on corresponding channel and
during an DMA operation.
When the specified number of transfers end
When operation is halted by a repeat area overflow
interrupt
When 0 is written to DA while DA = 1
(In block transfer mode, write is effective after end
of one-block transfer)
Reset, NMI interrupt, hardware standby mode
