14.1.1 Direct Connection

For digital input configuration pins, the available settings are to connect it either to VDD or GND.

The following configuration shows an example of how to connect a configuration pin to VDD:

Figure 14-1. Direct Connection to VDD

The following configuration presents an example of how to connect a configuration pin to GND:

Important: The pull-up and pull-down resistors are a precautionary recommendation, as the MTCH9010 liquid detector device will not pull the CFG_PIN to either VDD or GND during operation. In this case, the typical value used for the pull-up and pull-down resistors is 1 kΩ.
