      Digi Xtend RSSI PWM Module.
      For LPC21xx on the TWOG:
      - INPUT CAPTURE CAP0.3 on P0.29 (TWOG ADC5, 5V to 3.3V voltage divider)
      - INPUT CAPTURE CAP0.0 on P0.30 (TWOG ADC4, no voltage divider)

      Currently only available on LPC21xx arch.
      You must also load the module pwm_meas.xml
