No documentation is available for the 47M997, but it has the same device

ID as the 47M15x and 47M192 chips and seems to be compatible.



Fan rotation speeds are reported in RPM (rotations per minute). An alarm is

triggered if the rotation speed has dropped below a programmable limit. Fan

readings can be divided by a programmable divider (1, 2, 4 or 8) to give
