SBUF0
Serial Data Buffer 0. Data for Serial Port 0 is read from or written to this location. The serial transmit and receive
bits 70
buffers are separate registers, but both are addressed at this location.

ORDER
Set Bit Order for Transmit and Receive.
bit 3
0: Most significant bits first
1: Least significant bBits first
CPHA
Serial Clock Phase Control.
bit 2
0: Valid data starting from half SCK period before the first edge of SCK
1: Valid data starting from the first edge of SCK
ESS
Enable Slave Select.
bit 1
0: SS (P1.4) is configured as a general-purpose I/O (default).
1: SS (P1.4) is configured as SS for SPI mode. DOUT (P1.2) drives when SS is low, and DOUT (P1.2) is
high-impedance when SS is high.
CPOL
Serial Clock Polarity.
bit 0
0: SCK idle at logic low
1: SCK idle at logic high
