Communication interface characteristics
SPI - serial peripheral interface
Subject to general operating conditions for Vdd and Top.
SPI slave timing values
Values are guaranteed at 10 MHz clock frequency for SPI with both 4 and 3 wires, based on
characterization results, not tested in production.
Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both Input and output port.
When no communication is on-going, data on CS, SPC, SDI and SDO are driven by internal
pull-up resistors.
