Figure 23.1 shows a diagram of the connections between this module and the USB connectors.

This module incorporates a pull-up resistor for the D+ signal and a pull-down resistor for the D+

and D- signals. These signals can be pulled up or down using the DPRPU and DMRPD bits in

This module controls the terminal resistor for the D+ and D- signals during high-speed operation

and the output resistor for the signals during full-speed operation. This module automatically

switches the resistor after connection with the host controller or peripheral device by means of

reset handshake, suspended state and resume detection. If a disconnection from the host controller

or peripheral device is detected, this module should be initialized by a software reset.

When the function controller function is selected and the DPRPU bit in SYSCFG is cleared to 0

during communication with the host controller, the pull-up resistor (or the terminal resistor) of the

USB data line is disabled, making it possible to control the device connection and disconnection

using software with the USB cable being connected.

taken into consideration when

designing the D+ and D- lines.
