The Reset-n (active low) pin can be connected to an external reset source, see Figure 30 for a switch example. If the reset signal is
connected to an output signal it must be an open drain collector, see Figure 31. The Reset-n pin can be left unconnected if not used.

Figure 32 is a complete 5V host system interface example with an RGB LED and two switches (except the serial interface, see section

10.2.4 Reset
10.2.5 A Complete 5V Host System Interface
for information). The design is based on the LM339 Quad OP-amp instead of logic gates.
