Function ACMP_GPIOSetup

bsp/efm32/Libraries/emlib/src/em_acmp.c:216–227

/ * @brief * Sets up GPIO output from the ACMP. * * @note * GPIO must be enabled in the CMU before this function call, i.e. * @verbatim CMU_ClockEnable(cmuClock_GPIO, true); @endverbatim * * @param[in] acmp * Pointer to the ACMP peripheral register block. * * @param location * The pin location to use. See the datasheet for location to pin mappings. * * @param enable * Enab

 *   Invert output.
