Type Description
I PCM data input
O PCM data output
I/O PCM sync; can be master (output) or slave (input).
I/O USB (Host) data negative. Negative terminal of the
USB transceiver.
I/O USB (Host) data positive. Positive terminal of the USB
transceiver.
I UART clear-to-send. Active-low clear-to-send signal
for the HCI UART interface.
O UART request-to-send. Active-low request-to-send
signal for the HCI UART interface. BT LED control pin.
I UART serial input. Serial data input for the HCI UART
interface.
O UART serial output. Serial data output for the HCI
UART interface.

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.
