Type Description
I/O JTAG select: pull high to select the JTAG interface. If
the JTAG interface is not used this pin may be left
floating or connected to ground.
Note: See Table 26: “GPIO Alternative Signal
Functions,” on page 120 for the JTAG signal pins.
I XTAL oscillator input
O XTAL oscillator output
I External sleep clock input (32.768 kHz)
O Reference clock request (shared by BT and WLAN).
If not used, this can be no-connect.
O Bluetooth PA output
I SFLASH_CLK
I/O SFLASH_CSN
I/O SFLASH master input, slave output
I/O SFLASH master output, slave input
I FM radio antenna port
I FM radio auxiliary antenna port
O FM DAC output 1
O FM DAC output 2
I/O PCM clock; can be master (output) or slave (input)
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.
