AD2EN: ADC2 Enable Bit.
0: ADC2 Disabled. ADC2 is in low-power shutdown.
1: ADC2 Enabled. ADC2 is active and ready for data conversions.
AD2TM: ADC2 Track Mode Bit.
0: Normal Track Mode: When ADC2 is enabled, tracking is continuous unless a conversion
is in progress.
1: Low-power Track Mode: Tracking Defined by AD2CM2-0 bits (see below).
AD2INT: ADC2 Conversion Complete Interrupt Flag.
0: ADC2 has not completed a data conversion since the last time AD2INT was cleared.
1: ADC2 has completed a data conversion.
AD2BUSY: ADC2 Busy Bit.
Read:
0: ADC2 conversion is complete or a conversion is not currently in progress. AD2INT is set
to logic 1 on the falling edge of AD2BUSY.
1: ADC2 conversion is in progress.
Write:
0: No Effect.
1: Initiates ADC2 Conversion if AD2CM2-0 = 000b
When AD2TM = 0:
00: ADC2 conversion initiated on every write of ‘1’ to AD2BUSY.
01: ADC2 conversion initiated on overflow of Timer 3.
10: ADC2 conversion initiated on rising edge of external CNVSTR2 pin.
11: ADC2 conversion initiated on overflow of Timer 2.
When AD2TM = 1:
00: Tracking initiated on write of ‘1’ to AD2BUSY and lasts 3 SAR clocks, followed by con-
version.
01: Tracking initiated on overflow of Timer 3 and lasts 3 SAR clocks, followed by conver-
sion.
10: ADC2 tracks only when CNVSTR2 input is logic low; conversion starts on rising
CNVSTR2 edge.
11: Tracking initiated on overflow of Timer 2 and lasts 3 SAR clocks, followed by conversion.
AD2WINT: ADC2 Window Compare Interrupt Flag.
0: ADC2 Window Comparison Data match has not occurred since this flag was last cleared.
1: ADC2 Window Comparison Data match has occurred.
AD2LJST: ADC2 Left Justify Select.
0: Data in ADC2H:ADC2L registers are right-justified.
1: Data in ADC2H:ADC2L registers are left-justified.
