Channel Configuration
Set to use P1.x as ADC input.
Clear to use P1.x as standart I/O port.
Reserved
The value read from these bits are indeterminate. Do not set these bits.
Pseudo Idle Mode (Best Precision)
Set to put in idle mode during conversion
Clear to convert without idle mode.
Enable/Standby Mode
Set to enable ADC
Clear for Standby mode.
End Of Conversion
Set by hardware when ADC result is ready to be read. This flag can generate an
interrupt.
Must be cleared by software.
Start and Status
Set to start an A/D conversion.
Cleared by hardware after completion of the conversion
