Using unconnected analog pins in RA4M1 with arduino ide

I am trying to use the analog and digital pins of the platform, I was already able to configure and use the digital pins, but I have not been able to make the analog pins work, I have configured the pins in analog mode but at the time of reading I have not found how to do it, Does anyone have an example of how to do it?

I made this example to test the digital and analog pins but only the digital ones work

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  R_IOPORT_PinCfg(NULL,BSP_IO_PORT_04_PIN_11,IOPORT_CFG_PORT_DIRECTION_OUTPUT | IOPORT_CFG_PMOS_ENABLE);
  R_IOPORT_PinCfg(NULL,BSP_IO_PORT_00_PIN_04,IOPORT_CFG_PORT_DIRECTION_INPUT | IOPORT_CFG_ANALOG_ENABLE);
}

// the loop function runs over and over again forever
void loop() {
  R_IOPORT_PinWrite(NULL, BSP_IO_PORT_04_PIN_11, BSP_IO_LEVEL_HIGH);
  delay(3000);                      // wait for a second
  R_IOPORT_PinWrite(NULL, BSP_IO_PORT_04_PIN_11, BSP_IO_LEVEL_LOW);
  delay(1000);                      // wait for a second
  // R_IOPORT_PinRead(NULL, BSP_IO_PORT_00_PIN_04, BSP_IO_LEVEL_HIGH);
}

Are you trying to use them as digital pins or analog? You've tried to set it up as analog but you appear to be trying to read it as digital.

Look in the core at how analogRead works. Reading an analog signal will surely involve the ADC in some way.
