1. Measurement points are done at CMOS levels: 0.3 x VDD and 0.7 x VDD

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.
