Direct reading value PORT C DUE Arduino

Official Hardware Mega Due

Hello,
I need to read direct value on PORTC DUE Arduino by one command.
Reading ADC value (for example):

uint16_t value = ((X >> 4) & 0xFF00) | ( (X >> 2) & 0xFF);

On the Arduino DUE port C, in addition to the pins that are set as inputs for the AD7606 conversion- 16bit ADC, there are also pins that are set as outputs.

My questions:
Can I safely read the PIOC->PIO_PDSR register, which contains the 16-bit ADC conversion value (inputs) if some others pins on port C are set as outputs ?

Is it possible to read PIOC->PIO_PDSR when there is a combination of inputs and outputs on port C without the risk of destroying the DUE?

Are there any special precautions required when reading the PIOC->PIO_PDSR register if there are pins on port C configured as outputs?

Thanks in advance for your answer

Yes, it's a read only register, there is no harm reading it, regardless of whether pins are set as input or output. It will not interfere with outputs at all.
