VPOR is critical to the power-on reset. VPOR is the voltage level at which the reset condition is released and all the
registers and the I2C/SMBus state machine are initialized to their default states. The value of VPOR differs based
on the VCC being lowered to or from 0. Figure 19 and Table 3 provide more details on this specification.
