Chapter 14 Automatic Transfer Controller
To activate ATC1 in the software, first complete steps (1) to (6), then set the AT1ACT flag in
the AT1CNT0 register. After the AT1ACT flag is set, ATC1 is started and data transfer is
started. The hardware automatically clears AT1ACT flag when ATC1 is activated. On the
standard transfer mode, set a program that sets flags as much as the data transfer needs.
