ADC Control Register
CEN
7
The ADC Control register selects the analog input channel and initiates the analog-to-dig-
ital conversion.
CEN—Conversion Enable
0 = Conversion is complete. Writing a 0 produces no effect. The ADC automatically clears
this bit to 0 when a conversion has been completed.
1 = Begin conversion. Writing a 1 to this bit starts a conversion. If a conversion is already
in progress, the conversion restarts. This bit remains 1 until the conversion is complete.
Reserved—Must be 0.
VREF
0 = Internal voltage reference generator enabled. The VREF pin should be left uncon-
nected (or capacitively coupled to analog ground) if the internal voltage reference is
selected as the ADC reference voltage.
1 = Internal voltage reference generator disabled. An external voltage reference must be
provided through the VREF pin.
CONT
0 = Single-shot conversion. ADC data is output once at completion of the 5129 system
clock cycles.
1 = Continuous conversion. ADC data updated every 256 system clock cycles.
ANAIN—Analog Input Select
These bits select the analog input for conversion. For information on the Port pins avail-
able with each package style, see
unavailable analog inputs.
0000 = ANA0
0001 = ANA1
0010 = ANA2
