1, if INT value is above the high limit or below the low limit on the previous
conversion cycle, 0 otherwise. This bit is set (once only) if a THERM mode is
engaged as a result of INT temperature readings exceeding the INT THERM limit.
This bit is also set (once only) if THERM mode is disengaged as a result of internal
temperature readings going 5°C below Int THERM limit.

This bit is set (once only) if a THERM mode is engaged as a result of temperature
readings exceeding the THERM limits on any channel. This bit is also set (once
only) if THERM mode is disengaged as a result of temperature readings going 5°C
below THERM limits on any channel.
This bit is set (once only) if the fan turns on when in automatic fan speed control (AFC)
mode as a result of a temperature reading exceeding T
also set (once only) if the fan turns off when in automatic fan speed control mode.
Unused. Reads back 0.
This bit latches a chassis intrusion event.
When GPIO16 is configured as an input, this bit is set when GPIO16 is asserted.
(Asserted may be active high or active low depending on the setting in GPIO
configuration register.)
When GPIO16 is configured as an output, setting this bit asserts GPIO16. (Asserted
may be active high or active low depending on setting in GPIO configuration register.)
