Type Description
I
Used by PMU to power up or power down the internal
BCM4356 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.
I
Used by PMU to power up or power down the internal
BCM4356 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 disabled through programming.
