12.11 COMMUNICATION INTERFACE CHARACTERISTICS
12.11.1 SPI - Serial Peripheral Interface
Subject to general operating conditions for V
design simulation and/or characterisation 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 I/O port characteristics for more details on the input/output alternate function char-
acteristics (SS, SCK, MOSI, MISO).
