Hysteresis the remote diode temperature registers.

The default value is 10 ℃ and LSB denotes 1 ℃.

When temperature exceed the critical temperature

limit the OVER# pin will be activate and the

OVER# pin will be deactivate when temperature

below the critical temperature limit minus this

register value (CRITI_HYSTE).
