Mechanical and electrical specifications

2.4

Communication interface characteristics

2.4.1

SPI - serial peripheral interface

Subject to general operating conditions for Vdd and Top.

Figure 3. SPI slave timing diagram

1. When no communication is ongoing, data on SDO is driven by internal pull-up resistors.

Note:

Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both input and output

ports.
