ADCCON1—(ADC Control SFR #1)
The ADCCON1 register controls conversion and acquisition times, hardware conversion modes and power-down modes as
detailed below.

Bit
Name
Description
ADCCON1.7
MD1
The mode bits (MD1, MD0) select the active operating mode of the ADC as follows:
ADCCON1.6
MD0
MD1 MD0 Active Mode
00
ADC powered down
01
ADC normal mode
10
ADC powered down if not executing a conversion cycle
11
ADC standby if not executing a conversion cycle
Note: In power-down mode the ADC VREF circuits are maintained on, whereas all ADC peripherals are
powered down, thus minimizing current consumption.
ADCCON1.5
CK1
The ADC clock divide bits (CK1, CK0) select the divide ratio for the master clock used to generate the
ADCCON1.4
CK0
ADC clock. A typical ADC conversion will require 17 ADC clocks. The divider ratio is selected
as follows:
CK1
CK0 MCLK Divider
00

ADCCON1.3
AQ1
The ADC acquisition select bits (AQ1, AQ0) select the time provided for the input track-and-hold
ADCCON1.2
AQ0
amplifier to acquire the input signal, and are selected as follows:
AQ1
AQ0 #ADC Clks
00

ADCCON1.1
T2C
The Timer 2 conversion bit (T2C) is set by the user to enable the Timer 2 overflow bit be used as
the ADC convert start trigger input. ADC conversions are initiated on the second Timer 2 overflow.
ADCCON1.0
EXC
The external trigger enable bit (EXC) is set by the user to allow the external CONVST pin to be
used as the active low convert start input. This input should be an active low pulse (minimum
pulsewidth >100 ns) at the required sample rate.
