When the ADC is not used, it is possible to set it in standby mode by clearing bit ADEN
in ADCON register. In this mode its power dissipation is reduced.
An interrupt end-of-conversion will occurs when the bit ADEOC is activated and the bit
EADC is set. For re-arming the interrupt the bit ADEOC must be cleared by software.
Figure 62. ADC Interrupt Structure
1. Configure P1.2 and P1.3 in ADC channels
2. Start a standard conversion
3. Start a precision conversion (need interrupt ADC)
// configure channel P1.2 and P1.3 for ADC
// Enable the ADC
// The variable "channel" contains the channel to convert
// The variable "value_converted" is an unsigned int
// Clear the field SCH[2:0]
// Select channel
// Start conversion in standard mode
// Wait flag End of conversion
// Clear the End of conversion flag
// read the value
// The variable "channel" contains the channel to convert
// Enable ADC
