Typical Connection
Figure 17-5
shows a typical connection between two microcontrollers. The master controller
(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 opposite edge of the clock.
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 transmission:
• Master sends data — Slave sends dummy data
• Master sends data — Slave sends data
• Master sends dummy data — Slave sends data
