PRELIMINARY
17.4.
The SPI is accessed and controlled through four special function registers in the system controller: SPI0CN Control
Register, SPI0DAT Data Register, SPI0CFG Configuration Register, and SPI0CKR Clock Rate Register. The four
special function registers related to the operation of the SPI Bus are described in the following section.

CKPHA: SPI Clock Phase.
This bit controls the SPI clock phase.
0: Data sampled on first edge of SCK period.
1: Data sampled on second edge of SCK period.
CKPOL: SPI Clock Polarity.
This bit controls the SPI clock polarity.
0: SCK line low in idle state.
1: SCK line high in idle state.
Bits5-3: BC2-BC0: SPI Bit Count.
Indicates which of the up to 8 bits of the SPI word have been transmitted.

Bits2-0: SPIFRS2-SPIFRS0: SPI Frame Size.
These three bits determine the number of bits to shift in/out of the SPI shift register during
a data transfer in master mode. They are ignored in slave mode.
