when setting the extended address. However, it’s still nice to know how to
derive them.
Because CV 17 and 18 make up a paired CV, programming order is
important. CV 17 must be written to first, followed by a write to CV 18. The
decoder will ignore commands that attempt to program these registers out of
order or with values outside the allowed range of 0xC000 to 0xE7FF.
These CVs may be changed in service mode at any time, but in operations
mode only when CV 29, bit 5 is cleared (i.e., CV 1, Primary Address is
enabled).
Default Value: CV 17 = 192, CV 18 = 03 (Long Address 0003)
