8.4.2 Phase staggering (Slave mode)
In Slave mode with phase lock operation enabled, a phase shift with respect to the
incoming clock signal can be selected to distribute the switching moments over time. In
non-I
five different phase shifts (
bits (IB3[D1:D3]). See
pin MOD. An additional capacitor must be connected to pin SSM when
used (see
