The ReadTorque() method returns the torque ratio from a channel configured
for Torque Mode. See Section 4.5.2 for information on torque sensor
configuration. The other channel in the pair, which is configured for N-Pulse
Mode, is read using the Read() method described in Section 4.10.1. The
N-Pulse channel returns RPM.
If FIFO mode is enabled, you can read count register data from the FIFO with
the following call:
Table 4-6 summarizes what events will cause data to be stored in the FIFO for
each mode. The data will consist of various counter/timer registers and
optionally, the time stamp. Each returned parameter takes up one uInt32, and all
are returned in each call.
