Type Description
I/O
JTAG select. This pin must be
connected to ground if the
JTAG/SWD interface is not used. It must
be high to select
SWD OR JTAG. When JTAG_SEL = 1:
• GPIO_2 is TCK/SWCLK
• GPIO_3 is TMS/SWDIO
• GPIO_4 is TDIO
• GPIO_5 is TDO
• GPIO_6 is TRST_L
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).
O
Bluetooth PA output.
I
FM radio antenna port.
O
FM DAC output 1.
O
FM DAC output 2.
I/O
PCM or SLIMbus clock; can be master
(output) or slave (input).
I
PCM data input or SLIMbus transport
sensing.
O
PCM data output.
I/O
PCM sync; can be master (output) or
slave (input), or SLIMbus data.
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. BT RF disable
pin 2.
O
UART serial output. Serial data output
for the HCI UART interface.
