COMMUNICATION INTERFACE CHARACTERISTICS (cont’d)
Figure 97. SPI Slave Timing Diagram with CPHA = 1
Figure 98. 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 alternate function capability of the SPI’s data output line (MOSI in master
mode, MISO in slave mode) is released. In this case, the pin status depends on the I/O port configuration.
