ADCEN: ADC Enable Bit
0: ADC Disabled. ADC is in low power shutdown.
1: ADC Enabled. ADC is active and ready for data conversions.
ADCTM: ADC Track Mode Bit
0: When the ADC is enabled, tracking is always done unless a conversion is in process
1: Tracking Defined by ADSTM1-0 bits
ADCINT: ADC Conversion Complete Interrupt Flag
(Must be cleared by software)
0: ADC has not completed a data conversion since the last time this flag was cleared
1: ADC has completed a data conversion
ADBUSY: ADC Busy Bit
Read
0: ADC Conversion complete or no valid data has been converted since a reset. The falling
1: ADC Busy converting data
Write
0: No effect
1: Starts ADC Conversion if ADSTM1-0 = 00b
00: ADC conversion started upon every write of 1 to ADBUSY
01: ADC conversions taken on every overflow of Timer 3
10: ADC conversion started upon every rising edge of CNVSTR
11: ADC conversions taken on every overflow of Timer 2
ADWINT: ADC Window Compare Interrupt Flag
(Must be cleared by software)
0: ADC Window Comparison Data match has not occurred
1: ADC Window Comparison Data match occurred
ADLJST: ADC Left Justify Data Bit
0: Data in ADC0H:ADC0L Registers is right justified
1: Data in ADC0H:ADC0L Registers is left justified
edge of ADBUSY generates an interrupt when enabled.
