7.1.22. HSSI Hotplug Debug Port Status

Description: Provides per port hotplug status.
Note: Applicable only for E-Tile when DR is enabled.

Byte Offset: 0x11C

Addressing Mode: 32 bits

Bit Type Reset Description
31:16 RO FFFF Hotplug_paused per-port: Indicates the hotplug module is paused or disabled.
When the bit is 1b1, perform the PMA attribute read/write commands.
  • [16]-port 0 hotplug paused
  • [17]-port 1 hotplug paused
  • [18]-port 2 hotplug paused
  • [19]-port 3 hotplug paused
  • [20]-port 4 hotplug paused
  • [21]-port 5 hotplug paused
  • [22]-port 6 hotplug paused
  • [23]-port 7 hotplug paused
  • [24]-port 8 hotplug paused
  • [25]-port 9 hotplug paused
  • [26]-port 10 hotplug paused
  • [27]-port 11 hotplug paused
  • [28]-port 12 hotplug paused
  • [29]-port 13 hotplug paused
  • [30]-port 14 hotplug paused
  • [31]-port 15 hotplug paused
[15:0] RO 0 Hotplug_paused per-port:

1'b1 indicates successful detection of a valid signal when the XCVR is locked to data and the received signal eye is above the threshold. This remains 1'b1 after successful signal detection. It resets to 0x0 on restart, re-enable, or reset of the hotplug.
