Section 23 A/D Converter
• When A/D conversion on channel 2 is completed, the A/D conversion end
interrupt for CG0 (i.e. INTADCAnT0) is generated. If the circuit is operating
normally, the result of conversion will be 1/2 AV
DD
.
• When A/D conversion on channel 3 is completed, the A/D conversion end
interrupt for CG0 (i.e. INTADCAnT0) is generated. If the circuit is operating
normally, the result of conversion will be 2/3 AV
DD
.
When the diagnosis voltage of channel S/H circuit diagnostic is changed, set
ADCAnDGCTL0.ADCAnPSEL[2:0] bits to diagnosis voltage.
