BLUETOOTH POWER-UP SEQUENCE
The information in this document is subject to change without notice.
330-0045-R4.0
The following sequence describes device power up from shutdown. Only the Bluetooth 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'.
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.
Exceptions are CLK_REQ_OUT, SLOWCLK, XTALP, and AUD_xxx, which are failsafe and can
tolerate external voltages with no VDDS and DC2DC.
Notes:
1.
2.
3.
(A) After this sequence is completed, the device is in the low VIO-leakage state while in shutdown
The DC2DC(1.8V) signal can be monitored on BT_FUNC2 Module Pin (#41)
