Check for a clean 3.3V. If it reads low or fluctuating, trace back to the standby regulator or check for a shorted decoupling capacitor near the IC.
Handles radio frequency signals with high precision using built-in Low-Noise Amplifiers (LNAs) for reception and power amplifiers for transmission.
Corrupt data in the external EEPROM can cause the VCT micro-core to freeze during the boot sequence.
