6.5 Power Down Mode
There are two different ways to entry power down mode, using the PD line or register setting.
6.5.1 PD Line Power Down Mode
To place the PAN301A in a low power mode to meet USB suspend specification, raise the PD line at
least 700us. Then PD line can stay high, with the PAN301A in the shutdown state, or the PD pin can be
lowered, returning the PAN301A to normal operation.
