During power-on reset (POR), the default values are stored in the registers. A POR is initiated when power is first
applied to the part and the voltage on the VDD supply surpasses the POR level as specified in the electrical character-
istics.
When a bit is “set”, this means it’s at a logic ‘1’. When a bit is “cleared”, this means it’s at a logic ‘0’.
5.1
Main Control Register
The Main Control register controls the primary power state of the device (see Section 4.1, "Power States").
If more than one power state bit is set, the actual power state will be as shown in Table 5-3, "Power State Bit Overrides".
