Datasheet
4.1.1 General I/O
General I/O interfaces are used for different purposes between the WU firmware and the Host:
• Asynchronous data interface – configuration of the WU firmware or exchange transparent digital
information between the connected Bluetooth devices.
• Synchronous voice interface – exchange transparent voice information between the connected
Bluetooth devices.
• Bluetooth connectivity PIO interfaces – indication and disconnection of the established Bluetooth
connection.
• Emulate serial handshaking PIO lines interface – DTE or DCE serial handshake emulation between
the connected Bluetooth devices.
UART interface (Asynchronous data and configuration):

Active (TTL) Description
TX Output High UART transmit data
RX Input High UART receive data
RTS Output Low UART request to send
CTS Input Low UART clear to send
Voice interface:

Description
MIC_P Input (analogue) Microphone input positive
MIC_N Input (analogue) Microphone input negative
AUX_DAC Output (analogue) Microphone input bias
SPKR_P Output (analogue) Speaker output positive
SPKR_N Output (analogue) Speaker output negative
PIOs are used to control/monitor the Bluetooth connectivity of the WU firmware.
PIO
Signal
Direction
Active (TTL) Description
2 Input High
Request to close the current Bluetooth connection to the remote
device.
3 Output High
Indicates that a successful Bluetooth connection is established with a
remote device.
To prevent connections or to close the current Bluetooth connection PIO[2] can be set high.
PIO[3] is held low as long as there is no Bluetooth connection. As soon as a successful Bluetooth
connection has been established with a remote device, PIO[3] goes high.
PIOs can also be used to emulate serial handshaking lines between the connected Bluetooth devices.
Emulation can either be DTE or DCE.

While the handshaking lines are transparent to the data channel these I/O may also be used to transfer
digital signals between two Free2move devices running WU
