14.7.1. Enhanced “Joystick “Angle Formula
The enhanced “joystick” angle function is enabled by parameter ENORTH. Parameters are automatically
calculated when using the 90333BCT/ 9 points solver to optimize the shape of Betaout vs Alphaout in
accordance to the mechanical boundaries of the Joystick
14.8. Programmable Diagnostic Settings
14.8.1. OUTxDIAG Parameter
This OUT1DIAG, OUT2DIAG parameters define the behavior of the output in case of a diagnostic
situation.
14.8.2. RESONFAULT Parameter
This RESONFAULT parameter enables the soft reset when a fault is detected by the CPU when the
parameter is set to 1. It is recommended to set it to “1” to activate the self diagnostic modes (See section
15).
Note that in the User Interface (MLX90333UI), the RESONFAULT is a cluster of the following two bits, i.e.
the 2 bits are both disabled or both enabled:
It is recommended to set both EEPROM parameters to “0” to activate the self diagnostic modes
14.8.3. EEHAMHOLE Parameter
The EEHAMHOLE parameter disables the CRC check and memory recovery (Hamming code) check
when a fault is detected by the CRC when it is equal to 3131h. Melexis strongly recommends to set the
parameter to 0 (enable memory recovery). The parameter is set automatically to 0 by the solver function
“MemLock”.
