Configuring and Programming

6.3.1

Test Mode

The BM83 module can be configured by using the Config Tool and the firmware is programmed by using the isUpdate

tool. The following table provides the settings for configuring the BM83 module for Test mode or Application mode.

Note: The BM83 module provides Test mode, which allows customers to use existing module manufacturing and

testing equipment and flow to test the BM83 modules without reinvesting in new test equipment. New customers are

encouraged to use the new RF test modes defined for this device.

Test mode allows an external UART host to communicate with the BM83 using Bluetooth vendor commands over the

UART interface. The host can interface with the driver firmware on the BM83 module to perform TX/RX operations

and to collect/report Bit Error Rate (BER) and other RF performance parameters. These values can then be used to

accept/reject the device and/or calibrate the module.

6.3.2

2-wire JTAG Program and Debug

The BM83 (IS2083BM) provides physical interface for connecting and programming the memory contents, see the

following figure. For all the programming interfaces, the target device (IS2083BM) must be powered, and all required

signals must be connected. In addition, the interface must be enabled through a special initialization sequence.

Note: For more details on 2-wire prog/debug, refer to the IS2083 SDK User’s Guide and IS2083 SDK Debugger

User’s Guide .

ICSP TM

The 2-wire ICSP port can be used to program the memory content. This interface uses the following two

communication lines to transfer data to and from the BM83 (IS2083BM) device being programmed:

• Serial Program Clock (TCK_CPU)

• Serial Program Data (TDI_CPU)

These signals are described in the following sections. The following table describes the signals required for the 2-wire

ICSP interface.
