7
AD0EN
ADC0 Enable.
Function
0: ADC0 Disabled (low-power shutdown).
1: ADC0 Enabled (active and ready for data conversions).
6
BURSTEN
ADC0 Burst Mode Enable.
0: ADC0 Burst Mode Disabled.
1: ADC0 Burst Mode Enabled.
5
AD0INT
ADC0 Conversion Complete Interrupt Flag.
Set by hardware upon completion of a data conversion (BURSTEN=0), or a burst
of conversions (BURSTEN=1). Can trigger an interrupt. Must be cleared by soft-
ware.
4
3
AD0BUSY
AD0WINT
ADC0 Busy.
Writing 1 to this bit initiates an ADC conversion when ADC0CM[2:0] = 000.
ADC0 Window Compare Interrupt Flag.
Set by hardware when the contents of ADC0H:ADC0L fall within the window speci-
fied by ADC0GTH:ADC0GTL and ADC0LTH:ADC0LTL. Can trigger an interrupt.
Must be cleared by software.
2:0
ADC0CM[2:0]
ADC0 Start of Conversion Mode Select.
Specifies the ADC0 start of conversion source.
000: ADC0 conversion initiated on write of 1 to AD0BUSY.
001: ADC0 conversion initiated on overflow of Timer 0.
010: ADC0 conversion initiated on overflow of Timer 2.
011: ADC0 conversion initiated on overflow of Timer 3.
1xx: ADC0 conversion initiated on rising edge of CNVSTR.
