WL_REG_ON
I
Used by PMU to power up or
power down the internal
BCM4339 regulators used by
the WLAN section. Also, when
deasserted, this pin holds the
WLAN section in reset. This pin
has an internal 200 kΩ pull-
down resistor that is enabled by
default. It can be disabled
through programming.

BCM4339 regulators used by
the Bluetooth/FM section. Also,
when deasserted, this pin holds
the Bluetooth/FM section in
reset. This pin has an internal
200 kΩ pull-down resistor that
is enabled by default. It can be
