• Manufacturer Part Number: mlx90316
• Description: Rotary Position Sensor Ic
• Manufacturer: Melexis Company

14.6. Programmable Diagnostic Settings
14.6.1. RESONFAULT Parameter
This RESONFAULT parameter disables the soft reset when a fault is detected by the CPU when the
parameter is set to 1. By default, the parameter is set to “0” but it is recommended to set it to “1” to
activate the self diagnostic modes (See section 15).
Note that in the User Interface (MLX90316UI), the RESONFAULT is split in two bits:
14.6.2. EEHAMHOLE Parameter
The EEHAMHOLE parameter disables the memory recovery (Hamming code) check when a fault is
detected by the CRC when it is equal to 3131h. By default the parameter is set to 0 (enable memory
recovery).
14.7. Lock
14.7.1. MLXLOCK Parameter
MLXLOCK locks all the parameters set by Melexis.
14.7.2. LOCK Parameter
LOCK locks all the parameters set by the user. Once the lock is enabled, it is not possible to change the
EEPROM values anymore.
Note that the lock bit should be set by the solver function “MemLock”.
