AMM8A SSI & BiSS C-mode
Bit 7
Excessive temperature warning
This warning bit is set to high (=”1”) when the sensor temperature exceeds 90°-
95°C (194°-203°F). To clear the error, the sensor temperature must drop below
85°C (185°F).

[76-77, ro]
Register 76
Bit 0
Excessive temperature error
This error bit is set to high (=”1”) when the sensor temperature exceeds 100°-
105°C (212°-221°F). To clear the error, the sensor temperature must drop below
85°C (185°F).
