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
SYSCFG.
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.
