A/D Conversion Using Subclock
Introduction
This application note discusses A/D conversion in subactive mode. The subclock is generated by the subclock oscillator circuit that uses a 32.768-kHz crystal resonator. A variable resistor is connected to analog input pin 0 (AN0) and A/D conversion is carried out every 0.5 seconds, with the results of the A/D conversion being stored to on-chip RAM.
