Title CFG XTAL FTRIM
Summary
Timing for BlueCore01 is controlled by a crystal. This requires
trimming for new hardware. This command can be used to set a
new trim value either before a radiotest command is started or
while a test is already in operation; the change takes effect
immediately.
Crystal Trim (xtal_ftrim) is a number between 0 and 63
inclusive. This is not a permanent change.
