6.2.1. Bufferable write

If the write buffer is enabled and the processor performs a write to a bufferable area, the data is placed in the write buffer at FCLK speeds (BCLK if running with fastbus extension) and the CPU continues execution. The write buffer then performs the external write in parallel.

If the write buffer is full (either because there are already eight words of data in the buffer, or because there is no slot for the new address), the processor is stalled until there is sufficient space in the buffer.
