Adc12A Ch.n Interrupt Flag Register - Epson S1C17W18 Technical Manual

ADC12_nCFG.VRANGE[1:0] bits
Notes: • A/D conversion will not be performed if the ADC12_nCFG.VRANGE[1:0] bits = 0x0. Set
these bits to 0x3 to perform A/D conversion.
• Be aware that ADC circuit current I
to 0x3 when the ADC12_nCTL.BSYSTAT bit = 1.

These bits indicate the ADC12A interrupt cause occurrence status.
1 (R): Cause of interrupt occurred
0 (R): No cause of interrupt occurred
1 (W): Clear flag
0 (W): Ineffective
The following shows the correspondence between the bit and interrupt:
ADC12_nINTF.ADmOVIF bit: Analog input signal m A/D conversion result overwrite error interrupt
ADC12_nINTF.ADmCIF bit: Analog input signal m A/D conversion completion interrupt
