<!-- 2014-07-02 - Added the Description tag to show the informational text per request from SF WG -->
<Description>When observed with the front wheel to the right
of the pedals, a value of 0 degrees represents the angle when
the crank is in the 12 o'clock position and a value of 90
degrees represents the angle, measured clockwise, when the
crank points towards the front wheel in a 3 o'clock position.
The left crank sensor (if fitted) detects the 0? when the
crank it is attached to is in the 12 o'clock position and the
right sensor (if fitted) detects the 0? when the crank it is
attached to is in its 12 o'clock position; thus, there is a
constant 180? difference between the right crank and the left
crank position signals.</Description>

Significant Octet represents the eight bits numbered 0 to
7.</p>
