Group C Connections – Frame Sync Signals
Group C connections are used to route signals to frame sync inputs. The
SPORT frame sync inputs (when the SPORT is in slave mode) and the
frame sync inputs to the eight IDP channels are selected from the list of
Group C sources and set in the Group C registers.
Each of the frame sync inputs specified is connected to a frame sync
source based on the 5-bit values described in the Group C frame sync
sources, listed in
