2.3

Communication interface characteristics

2.3.1

SPI - serial peripheral interface

Subject to general operating conditions for Vdd and top.

Table 5.

SPI slave timing values

Figure 3.

SPI slave timing diagram (2)

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
