/* On EFM32ZG_STK3200, the DISPLAY driver Platform Abstraction Layer (PAL)
 * uses the RTC to time and toggle the EXTCOMIN pin of the Sharp memory
 * LCD per default. However, the watch example wants to use the RTC to
 * keep track of time, i.e. generate interrupt every second. Therefore
 * the watch example implements a function (rtcIntCallbackRegister)) that
 * enables the PAL to register the callback function that needs to be called in
 * order to toggle the EXTCOMIN pin.
 * I.e we need to undefine the INCLUDE_PAL_GPIO_PIN_AUTO_TOGGLE (which
 * is defined by default and uses the RTC) and we need to define the
 * PAL_TIMER_REPEAT_FUNCTION. */
