3.15 Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 18 Mbit/s in slave and master modes in full-
duplex and half-duplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame size is configurable from 4 bits to 16 bits.
SPI1 and SPI2 are identical and implement the set of features shown in the following table.
3.16 Serial wire debug port (SW-DP)
An ARM SW-DP interface is provided to allow a serial wire debugging tool to be connected
to the MCU.

2. Not available on STM32F030x4/6 devices.
3. Available only on STM32F030xC devices.
