(Processor 1) initiates the data transfer by sending the SCK signal. Data is shifted out of both
shift registers on their programmed clock edge, and latched on the edge of the clock specified by
the SMP bit. Both processors should be programmed to same Clock Polarity (CKP), then both
controllers would send and receive data at the same time. Whether the data is meaningful (or
dummy data) depends on the application software. This leads to three scenarios for data trans-
mission:
• Master sends data — Slave sends dummy data
• Master sends data — Slave sends data
• Master sends dummy data — Slave sends data
