WL_REG_ON
I
Used by PMU (OR-gated with
BT_REG_ON) to power up or power
down the internal BCM4330 regulators
used by the WLAN section. This pin is
also a low-asserting reset for WLAN only
(Bluetooth is not affected by this pin).
Logic High Level: 1.08V–3.6V
200k pull-down resistor included.

Auxiliary PMU control inputs (see
“Reset Circuits” on page 31). These pins
have 200k internal pull-down resistors
and should be no-connect when not
used.
