DTC Chain Transfer Enable
When this bit is set to 1, a chain transfer will be
performed. For details, refer to 8.5.4, Chain Transfer.
In data transfer with CHNE set to 1, determination of
the end of the specified number of transfers, clearing of
the interrupt source flag, and clearing of DTCER, are
not performed.
DTC Interrupt Select
When this bit is set to 1, a CPU interrupt request is
generated every time after the end of a data transfer.
When this bit is set to 0, a CPU interrupt request is
generated at the time when the specified number of
data transfer ends.
