Using pin 4 as analog input on R4 minima

Hardware

Hi everybody,
I need to use pin D4 as an analog input, indicated in the datasheet as AN019, but I don't know how to configure it.
Any suggestion ?
Thanks in advance

Your R4 Minima has the same six analog pins as my UNO, A0-A5.
D4 is a digital pin.

Try this.

#include <analog.h> // for analogRead(bsp_io_port_pin_t)

bsp_io_port_pin_t D4A = digitalPinToBspPin(4); 

void setup()
{
  Serial.begin(115200);
}

void loop()
{
  int val = analogRead(D4A);  
  Serial.println(val);
  delay(100);
}
