1. Values are guaranteed at 10MHz clock frequency for SPI with both 4 and 3 wires, based on characterization results, not
2. Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both Input and output port
3. When no communication is on-going, data on CS, SPC, SDI and SDO are driven by internal pull-up resistors
