7 - POWER MANAGEMENT
The device can be supplied by the USB bus
power lines VBUS (5 volts) and GNDBUS
(ground). This is enabled when RPSM (remote
power supply mode) is at logic one. Then on-chip
regulators bring 3.3 volts to internal analog and
digital blocks. When RPSM is high, a supply is
brought to external devices through pins GNDD1,
VREGD1, GNDD2, VREGD2, GNDA, VREGA.
The power budgeting is done by the host when
initializing the pipe:
The
needed
information
(maximum
power
consumption) is adjusted through pins CFG0,
CFG1 and as well as RPSM for “remote wake up
ability” information.
The following mechanism is used to do "a get
description device".
