t(s) 1. Measurement points are done at CMOS levels: 0.3xVDD and 0.7xVDD.

c 2. When no communication is on-going the data output line of the SPI (MOSI in master mode, MISO in slave

u mode) has its alternate function capability released. In this case, the pin status depends on the I/O port

d configuration.
