BLUETOOTH POWER-UP SEQUENCE

330-0041-Rev2.4
The following sequence describes device power up from shutdown. Only the BT core is enabled; the
WLAN core is disabled.
Power up requirements:
1. No signals are allowed on the IO pins if no IO power supplied, because the IOs are not 'failsafe'.
Exceptions are CLK_REQ_OUT, SLOWCLK, XTALP and AUD_xxx, which are failsafe and can tolerate
external voltages with no VDDS and DC2DC.
2. VDDS and SLOWCLK must be stable before releasing BT_EN.
3. Fast clock must be stable maximum 55 ms after BT_EN goes HIGH.
