Triaxis® Position Sensor Assembly
parameter adjusts the minimum output voltage level. The CLAMPHIGH parameter sets the maximum
output voltage level. Both parameters have 16 bits of adjustment and are available for both LNR modes.
In analog mode, the resolution will be limited by the D/A converter (12 bits) to 0.024%VDD. In PWM mode,
the resolution will be 0.024%DC.

15.4. Lock
The MEMLOCK write protects all the EEPROM parameters set by the Melexis and user. Once the lock is
enabled, it is not possible to change the EEPROM values anymore.
Note that the Memlock bits should be set by the solver function “MemLock" and is only applicable for the
ADD-version.

15.5.1. MAPXYZ
The MAPXYZ parameter defines which fields are used to calculate the angle. The different possibilities
are described in the tables below.
This 2 bits value selects the first (B1) and second (B2) field components according the table below.
