Channel 0 is a differential input to the MCP3905 device and is intended for the
current-sensing channel of the energy meter. Channel 0 on this evaluation board
contains resistor sockets for CT burden resistors, as well as a RC filter on each input,
with the option of shorting either input to ground. Two examples of jumper configuration
are given in Figure 2-8 and Figure 2-9.
