In slave mode you aren't in control of the clock that is demanding data, and it's going to be highly intolerant of any latency.
You must service any requests very quickly, and need to use DMA to provide the data to the bus.
Devices running at 8mbps are dumb state machines, implemented in hardware, with latencies measured in nanoseconds.
