What's the number of SPI interfaces I can configure on the BLE version? I don't see an explicit number in any of the obvious places in the datasheet, so presumably it depends on the chip.
Can somebody point me to an appropriate reference?
Thanks.

Yes, you are quite right: It depends on the chip. There are two distinct ways an SPI interface can be set up in a PSoC: Using an SCB (Serial Control Block) or an UDB (Universal Digital Block). In Creator at the very right hand side of the window is a "Resource Meter" that shows how many resources your selected chip has got and (after a successful built) how many of the resources are used/free.
When in need of SPI interfaces you may consider gating/multiplexing the signals (clock) to increase the number of slaves connected.
