Universal serial bus (USB)
The STM32F070xB/6 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 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)
看引脚说明20pin的你需要配置AFIO才可以使用。
On STM32F070x6 devices, pin pair PA11/12 can be remapped instead of pin pair PA9/10 using SYSCFG_CFGR1 register.
