Communication interface characteristics
SPI - serial peripheral interface
Subject to general operating conditions for Vdd and top.
Table 5.
1. Values are guaranteed at 10 MHz clock frequency for SPI with both 4 and 3 wires, based on
Figure 3.
3. When no communication is on-going, data on CS, SPC, SDI and SDO are driven by internal pull-up
a. Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both Input and Output port
