Timeout faults block the firewall only when their checking is enabled. The following timeout conditions can block the MI-side firewall:
- AWREADY_MAX_WAIT_TO
- AWREADY should be asserted within an NPI timebase period of AWVALID being asserted.
- WREADY_MAX_WAIT_TO
- WREADY should be asserted within an NPI timebase period of WVALID being asserted.
- ARREADY_MAX_WAIT_TO
- ARREADY should be asserted within an NPI timebase period of ARVALID being asserted.
- RVALID_MAX_WAIT_TO
- RVALID should be asserted within an NPI timebase period of either AR command transfer or previous R transfer while there are outstanding AR commands.
- WRITE_TO_BVALID_MAX_WAIT_TO
- BVALID should be asserted within an NPI timebase period of AW command transfer or WLAST transfer (whichever is later), or previous B transfer if there are yet more AW and WLAST transfers outstanding.
