interrupt enable bit MCSDIENn[SDIE[sd]] is set. To clear the interrupt flag, either write a one into
the related bit position MCSDIn[SDIF[sd]] or disable the related short-circuit detector by writing
zero to MCSDEn[SDEN[sd]]. If the short-circuit detector is enabled and a static short-circuit
exists, then the MCSDIn[SDIF[sd]] flag will be asserted directly after clearing it, because the
short-circuit detector is still enabled and will detect the short-circuit again. To avoid this behavior,
disable the short-circuit detector channel after detection of the short-circuit.
