Setting LSBF causes data to be transmitted LSB first (the default is
MSB first). LSBF does not affect bit positions in the data register;
reads and writes always have MSB in bit 7.
SPR2 adds a divide-by-4 prescaler to the SPI clock chain. With the
two bits in the SPCR, this specifies the SPI clock rate. See
