COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
Figure 91. SPI Slave Timing Diagram with CPHA=1
Figure 92. SPI Master Timing Diagram
Notes:
1. Measurement points are done at CMOS levels: 0.3xV
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.
