Register 0x6 allows the user to enable or disable any of the alarm flags that are not required. If disabled, that particular alarm no longer
flags on the appropriate open-drain pin; however, the alarm status is still available in both of the alarm status registers (Address 0x43 and
Address 0x44).

to have all or any information flagged to the alarm pin. The DUTGND pin has a 50 A pull-up to
allow for detection of an error in the DUTGND path. Setting this bit high also disables the 50 A
pull-up.
