4.27. Synchronous Peripheral Interface (SPI)
Two SPI ports, each of them with three chip selects, are available on the Stamp9261. The SPI baud
rate is Master Clock (MCK) divided by a value between 1 and 255.
rate is Master Clock (MCK) divided by a value between 1 and 255.
A receive and a transmit DMA channel is assigned to each of the two SPIs.
4.28. Synchronous Serial Controller (SSC)
The three Synchronous Serial Controllers of the SAM9261 processor are available which one to use
depends on the multiplexing of the pins with other devices used in the application.
depends on the multiplexing of the pins with other devices used in the application.
The SSC supports many serial synchronous communication protocols generally used in audio and
telecom applications such as I2S, Short Frame Sync, Long Frame Sync, etc.
telecom applications such as I2S, Short Frame Sync, Long Frame Sync, etc.
The SSC has separated receive and transmit channels. Each channel has a data, a clock and a frame
synchronization signal (RD, RK, RF, resp. TD, TK, TF).
