S, the SSI interface supports more synchronous modes.
Details are to be taken from the NXP Reference Manuals (4), (5), and (6).
3.2.5.3 CCM
The i.MX6 clock controller CCM provides two programmable clocks. The following table shows the signals of the CCM.

3.2.5.4 ECSPI
The i.MX6 provides five ECSPI interfaces. Primarily ECSPI1 and ECSPI5 are available at the connectors. The i.MX6 derivatives “Solo”
and “DualLite” do not provide ECSPI5. The following table shows the signals used by the ECSPI1 and ECSPI5 interfaces.
