ATR0621 [Preliminary]
The following settings apply if GPSMODE configuration is not enabled, that is, GPSMODE = 0
(ROM-Defaults):
3.3.4 USB Power Mode
For correct response to the USB host queries, the device has to know its power mode. This is
configured via GPSMODE7. If set to bus powered, an upper current limit of 100 mA is reported
to the USB host; that is, the device classifies itself as a “low-power bus-powered function” with
no more than one USB power unit load.
