Bit 0 (RBF): Read Buffer Full Flag
1 : Receiving completed, and SPIRB is fully exchanged.
0 : Receiving not completed, and SPIRB has not fully exchanged.

Bit 7 (CES): Clock Edge Select Bit
0 : Data shift out on rising edge, and shifts in on falling edge. Data is on
hold during low-level.
1 : Data shift out falling edge, and shift in on rising edge. Data is on hold
during high-level.
Bit 6 (SPIE): SPI Enable Bit
0 : Disable SPI mode
1 : Enable SPI mode
Bit 5 (SRO): SPI Read Overflow Bit
0 : No overflow
1 : A new data is received while the previous data is still being held in the
SPIRB register. In this situation, the data in SPIS register will be
destroyed. To avoid setting this bit, user is required to read the SPIRB
register although only the transmission is implemented. This can only
occur in slave mode.
