Hello Support,
Is there any limit that GPIO Port Pins cannot be used in software for multiple peripherals [Analog and Digital mode] at the same time?
I am assuming ALTIN signal as shown the attached picture always goes to all the intended Analog and Digital peripheral.
Only the software register contents for respective peripheral selects the value to be read or corresponding peripheral to function.
For example, in the example shown below, can we use the same pin for CAN Receive as well as ADC data capture of the same signal voltage along with some GTM Timer to measure waveform data?
Or, it is not allowed to switch on multiple peripherals on the same Input GPIO Pin because of internal architecture limitation?
Please provide some details.
Best Regards

Hello,
on the mixed analog-/digital pins, the digital functionality must be activated in the PDISC register.
The analog-input functionality can be always used.
Once configured for digital usage, all modules which receive the signal can be used at the same time to get data from this single pin.

as i know, some functions can be used simultaneosly on same pin.
