On page 89 of the Renesas RA6M5 specification, there is a sentence “The use of pins AN000 to AN010, AN012, AN013 as digital outputs is not allowed when the 12-Bit A/D converter is used.” If pins AN000 to AN010, AN012, AN013 ...Read more
On page 89 of the Renesas RA6M5 specification, there is a sentence “The use of pins AN000 to AN010, AN012, AN013 as digital outputs is not allowed when the 12-Bit A/D converter is used.”
If pins AN000 to AN010, AN012, AN013 are used as digital outputs when using ADC, what will be the impact and result?

As this is not allowed, the result is not specified in the data sheet. If the pins were used as inputs while the ADC is being used (with an Analog signal on the inputs), you would have the output of the device fighting with the input. This could cause many issues- from excess noise to possible overRead more

If the pins were used as inputs while the ADC is being used (with an Analog signal on the inputs), you would have the output of the device fighting with the input. This could cause many issues- from excess noise to possible over heating and even potential wear/damage to the device pins.
