15 SPI
The SoC implements two instances of a SPI controller. One controller supports Master
operation and another controller supports Slave operation.
15.1 Signal Descriptions
Please see Chapter 2, “Physical Interfaces” for additional details.
The signal description table has the following headings:
• Signal Name: The name of the signal/pin
• Direction: The buffer direction can be either input, output, or I/O
(bidirectional)
• Type: The buffer type found in Chapter 4, “Electrical Characteristics”
• Description: A brief explanation of the signal’s function
