Hello,
I plan to use ADC to monitor Vref+ (1.2V).
ADC channel A4 can be selected to monitor this voltage internally.
This 1.2-V reference voltage could also be output to I/O pin P1.4 by setting the corresponding PMM control register.
My question is: if I do not need to output Vref+ to P1.4, is it still possible to use this pin as a generic I/O pin while internally monitoring Vref+ through channel A4?
Many thanks.
Regards,
Mauro
