Detailed Description

Aggregate USBHS host-controller model state.

Aggregate USBHS host-model state.

The 16-bit reg shadow answers the plain register reads/writes; the staging buffers carry the bytes crossing the modelled cable. din holds the device's control-IN response (or a synthetic status ZLP); pout / pin hold the per-pipe bulk OUT / IN payloads. pipe_ep / pipe_maxp / pipe_pid mirror the per-pipe config the host programs through PIPESEL/PIPECTR.

The 16-bit reg shadow answers every register without special semantics; the per-pipe arrays are the PIPESEL-windowed configuration; stage accumulates CFIFO writes until BVAL commits them over the loop.

Invariant: stage_len <= k_usbhs_stage_cap.
