22.3.2
Figures 22.6 and 22.7 show example connections of the USB host controller and transceiver.
Figure 22.6 shows an example connection using the built-in transceiver 1. By using the
USB2_ovr_current, USB2_pwr_en, USB2_P, and USB2_M pins in an external circuit similar to
that in figure 22.6, you can also use built-in USB transceiver 2. Figure 22.7 shows an example
connection when not using the built-in USB transceiver. When using the USB host controller, a
separate LSI must be used for USB power bus control (equivalent to the USB power control LSIs
in figures 22.6 and 22.7). Make sure the LSI has the power supply capacity to satisfy the USB
standard, and select one that has an overcurrent protection function. Configure the system so that
the input to the USB1_ovr_current pin is Low on detection of an overcurrent.
