Bitbang is set to drive input/output buffers like bus switch from read
to write. Transfer sends the payload bistream. There are at least two
bitbangs per swd transaction, there might be three, this is why it is
so slow. The TAR autoincrement allows sending multiple data with one
setup, this way we send data at maximum speed, but still there are two
or three bitbangs per one data... it is not a problem on a GPIO but on
USB each transfer is a 1ms delay...
