2.1.7 J1 Configuration

If using separate I/O inputs, J1 is used to configure pin 8 to pull up to VIO or pull down to GND configuration. This pin can be pulled up to VIO by connecting a shunt to the PU (pull up) and STB pins (1 & 2) on J1, or it can be pulled down to GND by connecting a shunt to the PD (pull down) and STB pins (2 & 3) on J1.
