Figure 83. SPI master timing diagram
1. Measurement points are done at CMOS levels: 0.3V
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 of the I/O port
configuration.
