D4: T_CRIT mask for Remote temperature, when set to 1 a remote temperature reading that exceeds T_CRIT
setpoint will not activate the T_CRIT_A pin.
D3: T_CRIT mask, this bit must be set to a 1 before the T_CRIT setpoint is lowered below 127 in order for
T_CRIT_A pin to function properly.
D2: T_CRIT mask for Local reading, when set to 1 a Local temperature reading that exceeds T_CRIT setpoint
will not activate the T_CRIT_A pin.
D1: INT active state inversion. When INT Inversion is set to a 1 the active state of the INT output will be a logical
high. A low would then select an active state of a logical low.
D6 and D0: These bits are always set to 0 and reserved for future use. A write of 1 will return a 0 when read.
