A 1 indicates that the local THERM limit has been tripped.
A 1 indicates that the Remote 1 THERM limit has been tripped.
A 1 indicates that the THERM signal has been asserted for longer than the programmed
limit. Clear on Read. If THERM % Limit = 0x00 and THERM is asserted, it is reasserted
immediately.
A 1 indicates that the THERM signal has been asserted low as an input only.
A 1 indicates that the THERM pin has been asserted low as an output.

A 1 indicates that Fan 1 has stalled.
A 1 indicates that the fans are running at full speed due to an alarm condition, for
instance, when a THERM temperature limit is exceeded.

A 1 indicates that the ADM1033 has pulled the ALERT output pin low. This allows
polling of a single status register to determine if an ALERT condition in any of the status
registers has occurred.
