| Port Name | Package::Struct | Type | Act | Width | Description |
|---|
| range_check_overwrite | prim_mubi_pkg::mubi8 | uni | rcv | 1 | Overwrites all ranges and let all requests pass through. |
| ctn_tl_h2d | tlul_pkg::tl_h2d | uni | rcv | 1 | TL-UL input port (request part), synchronous |
| ctn_tl_d2h | tlul_pkg::tl_d2h | uni | req | 1 | TL-UL input port (response part), synchronous |

| deny_cnt_reached | Event | Deny counter has reached threshold. |
| Alert Name | Description |
|---|
| recov_ctrl_update_err | This recoverable alert is triggered upon detecting an update error in the shadowed Control Register. |
| fatal_fault | This fatal alert is triggered when a fatal TL-UL bus integrity fault is detected or the internal counter has an error. |
