CYW89035
1.1.4 Link Control Layer
The link control layer is part of the Bluetooth link control functions that are implemented in dedicated logic in the link control unit (LCU).
This layer consists of the command controller that takes commands from the software, and other controllers that are activated or
configured by the command controller, to perform the link control tasks. Each task is performed in a different state or substate in the
Bluetooth Link Controller.

1.1.5 Test Mode Support
The CYW89035 fully supports Bluetooth Test mode as described in Part I:1 of the Specification of the Bluetooth System Version 3.0.
This includes the transmitter tests, normal and delayed loopback tests, and reduced hopping sequence.
In addition to the standard Bluetooth Test Mode, the CYW89035 also supports enhanced testing features to simplify RF debugging
and qualification and type-approval testing. These features include:
■ Fixed frequency carrier wave (unmodulated) transmission
❐ Simplifies some type-approval measurements (Japan)
❐ Aids in transmitter performance analysis
■ Fixed frequency constant receiver mode
❐ Receiver output directed to I/O pin
❐ Allows for direct BER measurements using standard RF test equipment
❐ Facilitates spurious emissions testing for receive mode
■ Fixed frequency constant transmission
❐ 8-bit fixed pattern or PRBS-9
❐ Enables modulated signal measurements with standard RF test equipment
1.1.6 Frequency Hopping Generator
The frequency hopping sequence generator selects the correct hopping channel number based on the link controller state, Bluetooth
clock, and device address.
