Type Description
I/O
I²S clock, can be master (output) or
slave (input).
I/O
I²S data input.
I/O
I²S data output.
I/O
I²S WS; can be master (output) or slave
(input).
I/O
Bluetooth general-purpose I/O.
I/O
Bluetooth general-purpose I/O.
I/O
Bluetooth general-purpose I/O.
I/O
Bluetooth general-purpose I/O.
I
Used by PMU to power-up or power
down the internal BCM43455 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 BCM43455 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.
I/O
Bluetooth DEV_WAKE.
I/O
Bluetooth HOST_WAKE.
I
