Module to Module Interconnects
3.3.1 Interconnection overview
NOTE
Many of the module to module interconnects are handled by the
Trigger Mux module (TRGMUX). See the
TRGMUX for more
information.
The following table captures the module to module interconnections for this device that
are not handled by the TRGMUX.

3.3.2 Analog reference options
Several analog blocks have selectable reference voltages as shown in Table 3-2 . These
options allow analog peripherals to share or have separate analog references. Care should
be taken when selecting analog references to avoid cross talk noise.
