Hi-Speed USB peripheral controller
8.16.3 Bus-powered mode
In bus-powered mode (see Figure 16), VCC(3V3) and VCC(I/O) are supplied by the output of
the 5 V-to-3.3 V voltage regulator. The input to the regulator is from VBUS. On plugging the
USB cable, the ISP1583 goes through the power-on reset cycle. In this mode, OTG is
disabled.
