ADC0 Enable Bit.
0: ADC0 Disabled. ADC0 is in low-power shutdown.
1: ADC0 Enabled. ADC0 is active and ready for data conversions.
0: Burst Mode Disabled.
1: Burst Mode Enabled.
ADC0 Conversion Complete Interrupt Flag.
0: ADC0 has not completed a data conversion since AD0INT was last cleared.
1: ADC0 has completed a data conversion.
ADC0 Window Compare Interrupt Flag.
This bit must be cleared by software
0: ADC0 Window Comparison Data match has not occurred since this flag was last
cleared.
1: ADC0 Window Comparison Data match has occurred.
ADC0 Left Justify Select Bit.
0: Data in ADC0H:ADC0L registers is right-justified
1: Data in ADC0H:ADC0L registers is left-justified. This option should not be used
with a repeat count greater than 1 (when AD0RPT[1:0] is 01b, 10b, or 11b).
00: ADC0 start-of-conversion source is write of 1 to AD0BUSY.
01: ADC0 start-of-conversion source is overflow of Timer 1.
10: ADC0 start-of-conversion source is rising edge of external CNVSTR.
11: ADC0 start-of-conversion source is overflow of Timer 2.
