Up to two devices can be cascaded with no external decoding circuitry. Figure 19 illustrates the
configuration required to cascade two devices on the host bus (only the relevant cascading
signals are included in this figure, although all other signals must also be connected). All balls of
the cascaded devices must be wired in common, except for ID0. The ID ball values determine the
identity of each device – the first device is identified by connecting the ID ball as 0, and the
second device by connecting the ID ball as 1. Systems that use only one mDOC H3 should
connect ID0 to GND.
