COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
Figure 139. SPI Slave Timing Diagram with CPHA = 1
Figure 140. SPI Master Timing Diagram
Notes:
1. Measurement points are done at CMOS levels: 0.3 x V
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.
