Expand description

Bursts in flight before the master waits for responses.

HBM answers a write burst some cycles after its last beat. If the writer waited for each answer before starting the next frame it would idle for that whole round trip; allowing up to 16 unanswered bursts hides the latency. The cap bounds how far the writer can run ahead of writes the memory has confirmed.
