Description
EXDMA Active
Enables or disables data transfer on the
corresponding channel. When this bit is set to 1, this
indicates that an EXDMA 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 EXDMA operation, transfer is
halted. If this bit is cleared to 0 during an EXDMA
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
Note: The value written in the EDA bit may not be
When the specified number of transfers end
When operation is halted by a repeat area
overflow interrupt
When 0 is written to EDA while EDA = 1
(In block transfer mode, write is effective after
end of one-block transfer)
Reset, NMI interrupt, hardware standby mode
effective immediately.
