ADT7470 Status register 0x42

Hello ADI support.

I need you help.

Then temperature dropped bellow Tmin and the fan controller AD7470 stops the Fan, but the Norm (bit 3 Register 0x42) doesn't asserted high) only corresponding fan[n] A 1 indicates that Fan [n]  has dropped below min speed

I expect that if the Fan Controler stops the fan becouse of he reached Tmin the Norm (bit 3 Register 0x42) should be asserted high
