252 / 279 page ![]() Electrical characteristics ST72361xx-Auto 252/279 Doc ID 12468 Rev 3 Figure 118. SPI master timing diagram 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. 19.13 10-bit ADC characteristics Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified.
