The CYWUSB6941 radio control interface is the communication interface between the CYWUSB6941 transceiver and the
CYWUSB6942 WirelessUSB EX baseband. It consists of a data interface and a control interface for transmitting and receiving
data, and a serial interface for a control interface from the WirelessUSB baseband CYWUSB6941.
There are two subsections of the interface:
Nine signals are used in the RF data and control path, four in the serial radio control interface, and one system clock. All of the
signals are unidirectional. Direction is oriented to/from the CYWUSB6941 RF IC.
