Section 23 USB Pin Multiplex Controller
• D+ Pull-up Control
Page 760 of 1414
Control D+ pull-up by using USB1_pwr_en pin in the system when the connection—
notification (D+ pull-up) to USB host or hub is wished to be inhibited (i.e., during high-
priority processing or initialization processing).
The D+ pull-up control signal and USBF_VBUS pin input signal should be controlled by using
the USB1_pwr_en pin and the USB cable VBUS (AND circuit) as is shown in examples of
figures 23.2 and 23.3
D+ pull-up is inhibited when the USB1_pwr_en pin is low in examples of figures 23.3 and
23.5. Use an IC such that allows voltage application when system power is off (for example,
HD74LV1G126A) for the pull-up control IC (IC2 in figures 23.2 to 23.5).
(The UDC core in this LSI holds the powered state when USBF_VBUS pin is low, regardless
of the D+/D− state.)
