Bluetooth Power-up Sequence
The following sequence describes device power-up from shutdown. Only the BT core is enabled; the WLAN
are disabled.
1. No signals are allowed on the IO pins if no IO power supplied, because the IOs are not failsafe. Exceptions are CLK_REQ,
SLEEP_CLK, XTALP and PCM_xxx, which are failsafe and can tolerate external voltages with no VIO and DC2DC.
2. VIO and SLEEP_CLK must be stable before releasing BT ENABLE (BT_RESETX).
3. Fast clock must be stable maximum 55ms after BT ENABLE goes HIGH.
4. The duration of T1 is defined as the time from BT ENABLE=high until F
is valid (55 ms typical).
REF
5. The duration of T
is defined as the time from the rising edge of BT ENABLE to the falling edge of UART_RTS.
WAKE-UP
The WL1273L indicates completion of BT power up sequence by asserting RTS low. This occurs up to 100 ms after BT ENABLE
goes high.
