Section 25 USB 2.0 Host/Function Module (USB)
• Function that automatically clears the buffer memory after the data for the pipe specified at the
DnFIFO (n = 0 or 1) port has been read (DCLRM)
• NAK setting function for response PID generated by end of transfer (SHTNAK)
25.2 Input/Output Pins
Table 25.1 shows the pin configuration and pin functions of the USB.
When this module is not in use, handle the pins as follows.
• Be sure to apply power to the power-supply pins
• Connect DP, DM, and VBUS to USBDPV_SS
• Connect REFRIN to USBAPV_CC through a 5.6 kΩ ±1% resistor
• For USB_X1 and USB_X2, see section 4.3, Clock Operating Modes

I/O Function
I/O D+ I/O of the USB on-chip transceiver
This pin should be connected to the D+ pin
of the USB bus.
I/O D− I/O of the USB on-chip transceiver
This pin should be connected to the D- pin of
the USB bus.
Input USB cable connection monitor pin
This pin should be connected directly to the
Vbus of the USB bus. Whether the Vbus is
connected or disconnected can be detected.
If this pin is not connected with the Vbus of
the USB bus, it should be supplied with 5 V.
It should be supplied with 5 V also when the
host controller function is selected.
Note: Vbus is not provided to the connected
device.
Input Reference resistor connection pin
This pin should be connected to USBAPV
SS
through a 5.6 kΩ ±1% resistor.
