15.7.2. DIAG Level
Determines the reporting level (diagnostic low, diagnostic high) during start-up (both analog and PWM
mode), or during a fault reporting (Only in Analog mode).
In PWM mode, the fault reporting level shall in principle be 0 when the leading edge is a rising edge,
(resp. 1 for a falling edge) in order to detect the first cycle after start-up. MLX recommends then
DIAG Level = PWMPOL.
15.7.3. Field Strength Diagnostic
(i) FIELDTHRESHLOW
Defines the field strength limit under which a fault is reported.
The run-time field strength estimation (FieldStrength) is compared to 2⁸ * FIELDTHRESHLOW.
The sensitivity of FIELDTHRESHLOW is typically 1mT/LSB. By default it is programmed to 10mT
