Figure 2: Pin Assignment (Bottom View)
1. If PCM_CLK, and I2C_SCL are not used, it is recommended to mount a 33pF capacitor close to
each of the three pins to prevent interference from affecting RF’s performance. Other unused pins
and RESERVED pins should be kept open, and all GND pins should be connected to the ground.
1)
means that these pins cannot be pulled up before startup.
