8.3.9 Pin Diagrams

This section presents the I/O structure of all digital input and output pins.

8.3.9.1 Logic Level Input Pin (Internal Pulldown)

Figure 8-14 shows the input structure for the logic levels pins INHx, INLx, nSLEEP, SCLK and SDI. The input

can be driven with an external resistor to GND or an external logic voltage supply. It is recommended to pull

these pins low in device sleep mode to reduce leakage current through the internal pull-down resistors.
