Title PCM EXTERNAL LOOPBACK
Summary
Sets the PCM into external LOOPBACK mode, whereby the data
written to the PCM output is read again on the input pin. A check is
made that the data read back is the same (up to usual codec
transformations) as that written. The LOOP BACK consists of 512
bytes of random data.
The PCM port mode is selectable as PCM Mode (pcm_mode),
which is the same as for PCM LB
(radiotest_pcm_loop_back)
The external LOOP BACK may be a simple wire.

writes the results to an array.
Test Arguments
Start Channel (chan1) = 0 to 78 (default 0)
Finish Channel (chan2) = 0 to 78 (default 78)
Return Data A sequence of ten reports of the synthesiser (LO_TUNE) error
voltage over the next 200µs.
Exit Click on Reset Chip or another routine being called.

Appendix 2
Known Software Issue(s) in BlueTest Version 1.4
(a) Pressing the Reset Chip button on the GUI while data is being transmitted sends a
hardware reset command to the chip and restarts the serial stack software.
Closing the GUI sends a hardware reset command to the chip.
If the link fails, the connection can only be recreated by manually resetting the chip
(power off/on) and by clicking on Reset Chip or closing down and restarting the GUI (both
of which will restart the serial stack software).
The above will not occur if no data is visibly scrolling in the window.
The tests concerned are:
g VCOTRIM
g BUILD LUT
g READ
g LUT
(b) There is a race between command responses indicating that a test has started and the
first data relating to that test. This does not affect the test results.
(c) It is not possible to rouse the chip from Deep Sleep except by powering down the chip
and restarting.

Operation is subject to the two following conditions :-
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications to the transmitter not expressively approved by CSR could void
the authority ability to operate the equipment.
User Label Warning !
The transmitter is in compliance with the Part 15 FCC Rules. A label which demonstrates
compliance with the FCC is located on the bottom of the laptop.
