13.11 COMMUNICATION INTERFACE CHARACTERISTICS
13.11.1 SPI - Serial Peripheral Interface
Subject to general operating conditions for V

Figure 88. SPI Slave Timing Diagram with CPHA=0
Notes:
1. Data based on design simulation and/or characterisation results, not tested in production.
2. 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.
3. Measurement points are done at CMOS levels: 0.3xV
