Note:

1. GPIO_0 and WL_DEV_WAKE signals are selected by using software.

2. SDIO_PADVDDIO = 1 (not in straps table) is set to 3.3V by default for all packages.

3. GPIO_7 can be used as WL_LED in WLBGA package.

a. For all new designs, use GPIO_6 for SECI_IN instead of GPIO_4. For existing designs, GPIO_4 can be still used for SECI_IN provided the strapping requirements discussed in “

WLAN/

BT GPIO Signals and Strapping Options” are fully satisfied.
