Analog Input Muxing
10.13.2 Analog Input Select Register
This register controls the analog muxes that feed signals
in from port pins into each Analog Column. Each of the
Analog Columns can have up to four port bits connected
to its muxed input. Analog Columns 01 and 02 (ACI1 and
ACI2) have additional muxes that allow selection
between separate column multiplexers (see Analog Input
Muxing diagram above). The AC1Mux and AC2Mux bit
fields control the bits for those muxes and are located in
the Analog Output Buffer Control Register (ABF_CR).
There are four additional analog inputs that go directly
into the Switch Capacitor PSoC blocks.
