ORDn
This bit in the same bit position with USInS1. The MSB of the data byte is transmitted
first when set to ‘1’ and the LSB when set to ‘0’ (only SPI mode)

CPHAn
This bit is in the same bit position with USInS0. This bit determines if data are
sampled on the leading or trailing edge of SCKn (only SPI mode).
