Volume 3—Signal Electrical and Timing Characteristics—C2000 Product Family
Serial Peripheral Interface (SPI) Bus Interface
Note:
SPI_MISO - t184 and t185 are referencing clock edge where the SoC will sample the SPI_MISO pin. The
slave transmitted this bit on the previous falling clock edge which is not shown.
