Section 22 USB Pin Multiplex Controller

22.3.1
Figures 22.2 to 22.5 show example connections of USB function controller and transceiver.
Figures 22.2 and 22.3 show connections when using the built-in USB transceiver. Figures 22.4
and 22.5 show connections when not using the built-in USB transceiver. When using the USB
function controller, the signals must be input to the cable connection monitor pin UJBF_VBUS.
The USBF_VBUS pin is multiplexed with the USB1_ovr_current pin, and writing 1 to bit 0 of the
EXPFC register selects the USBF_VBUS pin functions. According to the status of the
USBF_VBUS pin, the USB function controller recognizes whether the cable is
connected/disconnected. Also, pin D+ must be pulled up in order to notify the USB host/hub that
the connection is established. The sample circuits in figures 22.2 to 22.5 use the USB1_pwr_en
pin for pull-up control.
