ANALOG TO DIGITAL CONVERTER
7
Using a port D pin as both an analog and digital input simultaneously is prohibited. When the ADC
is enabled (ADON=1) and one of channels 0 to 5 is selected, the corresponding Port D pin will
appear as a logic zero when read from the Port Data Register.
7.3
ADC Data Register (ADDR)
The ADDR stores the result of a valid ADC conversion when the COCO bits is set in ADSCR.
7.4
ADC during Low Power Modes
The ADC continues normal operation in WAIT mode. To reduce power consumption in WAIT
mode, the ADON and ADRC bits in the ADSCR should be cleared if the ADC is not used. If the
ADC is in use and the internal bus clock is above 1MHz, it is recommended that the ADRC bit be
cleared.
In STOP mode, the ADC stops operation.
