PRODUCTION DATA
The OT_FAULT_LIMIT command sets the value of the temperature limit, in degrees Celsius, that causes an overtemperature fault condition when the sensed temperature from the external sensor exceeds this limit. The default value is selected inMFR_SPECIFIC_13, using the OTF_DFLT bit. Refer to the device Technical Reference Manual for more information. OT_FAULT_LIMIT is a linear format command, and must be accessed through Read Word/Write Word transactions. OT_FAULT_LIMIT is a paged register. In order to access OT_FAULT_LIMIT command for channel A, PAGE must be set to 00h. In order to access OT_FAULT_LIMIT register for channel B, PAGE must be set to 01h. For simultaneous access of channels A and B, the PAGE command must be set to FFh.
