CSR8615 QFN provides a debug SPI interface for programming, configuring (PS Keys) and debugging the CSR8615
QFN. Access to this interface is required in production. Ensure the 4 SPI signals and the SPI_PCM# line are brought
out to either test points or a header. To use the SPI interface, the SPI_PCM# line requires the option of being pulled
high externally.
CSR provides development and production tools to communicate over the SPI from a PC, although a level translator
circuit is often required. All are available from CSR.
7.3.1 Multi-slave Operation
Avoid connecting CSR8615 QFN in a multi-slave arrangement by simple parallel connection of slave MISO lines.
When CSR8615 QFN is deselected (SPI_CS# = 1), the SPI_MISO line does not float. Instead, CSR8615 QFN
outputs 0 if the processor is running or 1 if it is stopped.
