Communication interface characteristics
Serial peripheral interface (SPI)
The following characteristics are ubject to general operating conditions for V
unless otherwise specified. The data is based on design simulation and/or characterization
results, not tested in production.
When no communication is on-going the data output line of the SPI (MOSI in master mode,
MISO in slave mode) has its alternate function capability released. In this case, the pin
status depends on the I/O port configuration. Refer to the I/O port characteristics for more
details on the input/output alternate function characteristics (SS, SCK, MOSI, MISO).
