The BP-CC3351 provides two clock inputs to the CC3351 device:
If the user desires to provide the own external slow clock through the Slow Clock Input pin (P2.19), then some re-work must be performed. The Y2 oscillator needs to be removed, and populate a 0201 sized, 0 ohm resistor on R29 pad. See Figure 3-8. The slow clock can also be generated internally to save on BOM.
