This pin is an input and sets logic thresholds. It also powers the pads of the following logic
pins:
AGND, CGND and DGND are ground pins for analog, charge pump and digital circuits,
respectively. These pins can be connected separately or together depending on the
system performance requirements.
There are four types of modes in the ISP1301:
Power modes of the ISP1301 are as follows:

Active power mode: power is on.
USB suspend mode: to reduce power consumption, the USB differential receiver is
powered down.
Global power-down mode: set bit GLOBAL_PWR_DN = 1 of the Mode Control 2
register; the differential transmitter and receiver, clock generator, charge pump, and
all biasing circuits are turned off to reduce power consumption to the minimum
possible; for details on waking up the clock, see
