8.12.1 Power-Up Sequencing

For proper start-up of the CC3120MOD module, perform the recommended power-up sequencing as follows:

  1. Tie VBAT1 (pin 37) and VBAT2 (pin 40) together on the board.
  2. Hold the nRESET pin low while the supplies are ramping up.

Figure 8-6 shows the reset timing diagram for the first-time power-up and reset removal.
