SPIC:
SPI Control Register.
Bit 7 (CES):
Clock Edge Select bit
0 = Data shifts out on rising edge, and shifts in on falling edge. Data is on hold
during the low level.
1 = Data shifts out on falling edge, and shifts in on rising edge. Data is on hold
during the 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 on hold in the
SPIB register. Under this condition, the data in SPIS register will be destroyed.
To avoid setting this bit, users should read the SPIRB register even if the
transmission is implemented only.
NOTE
This can only occur under slave mode.
Bit 4 (SSE):
SPI Shift Enable bit
0 = Reset as soon as the shifting is completed and the next byte is ready to shift.
1 = Start to shift, and stays on 1 while the current byte continues to transmit.
NOTE
This bit can be reset by hardware only.
