STM32F103vct6的usb支持内部上拉电阻不？

The STM32F072x8/xB embeds a full-speed USB device peripheral compliant with the USB
specification version 2.0. The internal USB PHY supports USB FS signaling, embedded DP
pull-up and also battery charging detection according to Battery Charging Specification
Revision 1.2. The USB interface implements a full-speed (12 Mbit/s) function interface with
added support for USB 2.0 Link Power Management. It has software-configurable endpoint
setting with packet memory up-to 1 KB (the last 256 byte are used for CAN peripheral if
enabled) and suspend/resume support. It requires a precise 48 MHz clock which can be
generated from the internal main PLL (the clock source must use an HSE crystal oscillator)
or by the internal 48 MHz oscillator in automatic trimming mode. The synchronization for this
oscillator can be taken from the USB data stream itself (SOF signalization) which allows
crystal-less operation.
