14.6.1. RESONFAULT Parameter
This RESONFAULT parameter enables 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:
• DRESONFAULT: disable the reset in case of a fault.
• DOUTINFAULT: disable output in diagnostic low in case of fault.
14.6.2. EEHAMHOLE Parameter
The EEHAMHOLE parameter disables the CRC check and the memory recovery (Hamming code) when it
is equal to 3131h. Melexis strongly recommends to set the parameter to 0 (enable memory recovery).
This is done automatically when using the MEMLOCK function.
