PRODUCTION DATA.
The OT_WARN_LIMIT command sets the temperature, in degrees Celsius, of the unit at which it should indicate an Over-temperature Warning event. OT_WARN_LIMIT is a linear format command, and must be accessed through Read Word/Write Word transactions. OT_WARN_LIMIT is a paged register. In order to access OT_WARN_LIMIT command for channel A, PAGE must be set to 00h. In order to access OT_WARN_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.
In response to the OT_WARN_LIMIT being exceeded, the device will:
