The tutorial in this section is intended as a supplement to the example code and
the API reference manual.
To configure a Revision 1 board, populate DQ_VR608_CFG structure using the
DqAdv608SetCfg() function. To configure a Revision 2 board, populate a
DQ_VR608_CFG_R2 structure via DqAdv608SetCfgExt().
DNx-VR-608 configuration parameters apply to either an individual channel (C),
a pair of channels (P), or the entire board/layer (L). The parameters, their
application scope (C/P/L), and supported revision(s) are listed in Table 5-2.
Some parameters take in a single value and some accept a logically grouped
combination of constants. Please refer to the "PowerDNA API Reference
Manual" for a complete description of each parameter.

DNx-VR-608 Variable Reluctance Interface
Programming with the Low-level API
Description
OR in flags to change associated

parameters
Analog input rate for the board

Rate at which data is stored in Timed Mode

Zero crossing level for ZC_FIXED. If the
desired zero crossing level is 0 V, UEI
recommends setting

slightly above 0 to avoid false positives,
e.g., 0.1 V.
Peak threshold divider for APT_LOGIC

Moving average for ZC_LOGIC and

APT_LOGIC
Output signals on Sync [3:0]

Output signals on DOut [3:0]

Number of teeth on the wheel for RPM

calculation
Number of missing or fused teeth

Configure open circuit, stalled rotation, and
overspeed alarms. Open circuit alarms do

not apply to TTL inputs.
Torque sensor polarity and rotation direction

Route DIn[3:0] to internal counters

Set noise floor level for the stall alarm. The
value is a point on the input range. Input

values below this point are ignored
Configure dividers on digital outputs

Set TPPM timeout in 10 ms increments
