ANAIN[3:0]—Analog Input Select
These bits select the analog input for conversion. Not all Port pins in this list are available
in all packages for the Z8 Encore! XP
able with each package style, see
analog inputs. Usage of these bits changes depending on the buffer mode selected in
Control/Status Register
For the reserved values, all input switches are disabled to avoid leakage or other undesir-
able operation. ADC samples taken with reserved bit settings are undefined.
