Description
DTC Chain Transfer Enable
Specifies the chain transfer. For details, see section
12.5.7, Chain Transfer. The chain transfer condition is
selected by the CHNS bit.
0: Disables the chain transfer
1: Enables the chain transfer
DTC Chain Transfer Select
Specifies the chain transfer condition. If the following
transfer is a chain transfer, the completion check of the
specified transfer count is not performed and activation
source flag or DTCER is not cleared.
0: Chain transfer every time
1: Chain transfer only when transfer counter = 0
DTC Interrupt Select
When this bit is set to 1, a CPU interrupt request is
generated every time after a data transfer ends. When
this bit is set to 0, a CPU interrupt request is only
generated when the specified number of data transfer
ends.
DTC Transfer Mode Select
Specifies either the source or destination as repeat or
block area during repeat or block transfer mode.
0: Specifies the destination as repeat or block area
1: Specifies the source as repeat or block area
