COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
Figure 92. SPI Slave Timing Diagram with CPHA=11)
Figure 93. SPI Master Timing Diagram 1)
Notes:
1. Measurement points are done at CMOS levels: 0.3xVDD and 0.7xVDD.
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.
