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