AD1EN: ADC1 Enable Bit.
0: ADC1 Disabled. ADC1 is in low-power shutdown.
1: ADC1 Enabled. ADC1 is active and ready for data conversions.
AD1TM: ADC1 Track Mode Bit.
0: Normal Track Mode: When ADC1 is enabled, tracking is continuous unless a conversion is in pro-
cess.
1: Low-power Track Mode: Tracking Defined by AD1STM2-0 bits (see below).
AD1INT: ADC1 Conversion Complete Interrupt Flag.
This flag must be cleared by software.
0: ADC1 has not completed a data conversion since the last time this flag was cleared.
1: ADC1 has completed a data conversion.
AD1BUSY: ADC1 Busy Bit.
Read:
0: ADC1 Conversion is complete or a conversion is not currently in progress. AD1INT is set to logic
1 on the falling edge of AD1BUSY.
1: ADC1 Conversion is in progress.
Write:
0: No Effect.
1: Initiates ADC1 Conversion if AD1STM2-0 = 000b
AD1CM2-0: ADC1 Start of Conversion Mode Select.
AD1TM = 0:
000: ADC1 conversion initiated on every write of ‘1’ to AD1BUSY.
001: ADC1 conversion initiated on overflow of Timer 3.
010: ADC1 conversion initiated on rising edge of external CNVSTR.
011: ADC1 conversion initiated on overflow of Timer 2.
1xx: ADC1 conversion initiated on write of ‘1’ to AD0BUSY (synchronized with ADC0 software-
commanded conversions).
AD1TM = 1:
000: Tracking initiated on write of ‘1’ to AD1BUSY and lasts 3 SAR1 clocks, followed by conver-
sion.
001: Tracking initiated on overflow of Timer 3 and lasts 3 SAR1 clocks, followed by conversion.
010: ADC1 tracks only when CNVSTR input is logic low; conversion starts on rising CNVSTR edge.
011: Tracking initiated on overflow of Timer 2 and lasts 3 SAR1 clocks, followed by conversion.
1xx: Tracking initiated on write of ‘1’ to AD0BUSY and lasts 3 SAR1 clocks, followed by conver-
sion.
UNUSED. Read = 0b. Write = don’t care.
