* Shutdown mode to reduce its power consumption down to 150nA.
*
* This file provides connectivity information on LEDs, Buttons, UART and

* \name ADC configuration
*
* These values configure which CC2538 pins and ADC channels to use for the ADC
* inputs. By default the RE-Mote allows two out-of-the-box ADC ports with a
* phidget-like 3-pin connector (GND/VDD/ADC)
*
* The RE-Mote allows both 3.3V and 5V analogue sensors as follow:
*
* - ADC1 (PA5): up to 3.3V.
* - ADC2 (PA4): up to 3.3V
* - ADC3 (PA2): up to 5V, by means of a 2/3 voltage divider.
*
* Also there are other ADC channels shared by default with Micro SD card and
* user button implementations:
*
* - ADC4 (PA6): up to 3.3V.
* - ADC5 (PA7): up to 3.3V.
* - ADC6 (PA3): up to 3.3V.
*
* ADC inputs can only be on port A.
* All ADCx are exposed in JP5 connector, but only ADC1 and ADC3 have GND and
* VDD (3/5V) pins next to it, so these can be exposed into a 3-pin phidget-like
* connector, for ADC2 either solder a wire to connect, or use a 4-pin connector
* to expose both ADC1 and ADC2 in a single connector, but this will leave no
* space for a ADC3 connector.
*
* The internal ADC reference is 1190mV, use either a voltage divider as input,
* or a different voltage reference, like AVDD5, or externally using PA7/AIN7
* and PA6/AIN6 configurable as differential reference, by removing the R26 and
* R33 0Ohm resistors to disconnect off the Micro-SD, and those will be
* accessible from JP5 connector.
*
* To enable the ADC[2,4-6], remove any 0Ohm resistors if required (see above),
* and define in your application `ADC_SENSORS_CONF_ADCx_PIN` and set its
* value with the corresponding pin number (i.e ADC2 to 4 as mapped to PA4).
* To disable any ADC[1-6] just define as above, but set to (-1) instead.
* Warning: if using ADC6 (PA3), you will need to disable the bootloader by
* making FLASH_CCA_CONF_BOOTLDR_BACKDOOR equal to zero
