F0 cube library's SPI API has problems.
In spite of running 8 bit transmission mode, the library transmit a 16 bit data.
So the misalignment check routine does not filter the unaligned address on 8 bit mode.
Then, I think this 8 bit transmission code does not communicate with 16 bit transmission,
the way F4 cube library works.
It's not welcome method, because user can not expect inside 16 bit transmission of the SPI API functions.
