103 SPI_SS_N behavior differs depending on Motorola SPI, TI SSP, or Microwire operational mode.
104 The capture edge differs depending on the operational mode. For Motorola SPI, the capture edge can be the rising or falling edge depending on the scpol register bit; for TI SSP, the capture edge is the falling edge; for Microwire, the capture edge is the rising edge.
105 Valid values of rx_sample_dly range from 1 to 64 (units are in Tspi_ref_clk steps).
