Default settings of AD5100-0 evaluation model only.
V 2MON must be 0 V (that is, V 2MON must be configured in edge sensitive mode) for software power-down.
These register bits are set only. To clear them, the AD5100 must be power cycled. In some cases, the AD5100 can be connected to an I 2 C bus with lots of activity.
Setting these bits is an added means of ensuring that any erroneous activity on the bus does not cause AD5100 special functions to become active.
