AnnaBridge 156:ff21514d8981 56 * The current digital-to-analog converter (IDAC) can source or sink a configurable
AnnaBridge 156:ff21514d8981 57 * constant current, which can be output on, or sinked from pin or ADC. The current
AnnaBridge 156:ff21514d8981 58 * is configurable with several ranges of various step sizes. The IDAC can be used
AnnaBridge 156:ff21514d8981 59 * with PRS and it can operate down to EM3.
AnnaBridge 156:ff21514d8981 60 *
AnnaBridge 156:ff21514d8981 61 * The following steps are necessary for basic operation:
AnnaBridge 156:ff21514d8981 62 *
AnnaBridge 156:ff21514d8981 63 * Clock enable:
AnnaBridge 156:ff21514d8981 64 * @include em_idac_clock_enable.c
AnnaBridge 156:ff21514d8981 65 *
AnnaBridge 156:ff21514d8981 66 * Initialize the peripheral with default settings and modify selected fields such as
