Starting Channel for Auto-Scan.
Sets the first CS0 channel to be selected by the mux for Capacitive Sense conver-
sion when auto-scan is enabled and active. All channels detailed in CS0MX SFR
Definition 8.15 are possible choices for this register.
When auto-scan is enabled, a write to CS0SS will also update CS0MX.
Ending Channel for Auto-Scan.
Sets the last CS0 channel to be selected by the mux for Capacitive Sense conver-
sion when auto-scan is enabled and active. All channels detailed in CS0MX SFR
Definition 8.15 are possible choices for this register.
