B Bit 7: ADCEN, ADC Enable.
0: Clear to turn off the ADC block.
1: Set to turn on the ADC block. At least 5us ADC enabled time is required before set ADCS.
Bit 6: ADCWI, ADC Window Compare Interrupt flag.
0: ADC0 Window Comparison Data match has not occurred since this flag was last cleared. The flag
must be cleared by software.
1: This flag is set when ADC Window Comparison Data match has occurred. An interrupt is invoked if it is
enabled. The interrupt on this flag can be enabled by EADCWI. (ADCFG1.6)
Bit 5: CHS3. Combined CH2~0 to select ADC input channel.
Bit 4: ADCI, ADC Interrupt Flag.
0: The flag must be cleared by software.
1: This flag is set when an A/D conversion is completed. An interrupt is invoked if it is enabled. The
interrupt on this flag can be blocked by IGADCI (ADCFG1.7).
Bit 3: ADCS. ADC Start of conversion. 0: ADCS cannot be cleared by software.
1: Setting this bit by software starts an A/D conversion. On completion of the conversion, the ADC
hardware will clear ADCS and set the ADCI. A new conversion may not be started while either ADCS or
ADCI is high.
Bit 2~0: CHS2 ~ CHS1, Input Channel Selection for ADC analog multiplexer.
