| Port Name | Clock Domain | I/O | Description |
|---|---|---|---|
| enc_egr_prtif_crypto_auth_only_p0 | enc_egr_axis_clk | O | PortIF Egress Encryption Authenticate Only: This is the authentication-only indication signal for the non-bypass packet which starts on segment 0 or 1.

| stat_rsvd_out_tx_top[119:0] | enc_egr_axis_clk | O | Bit [65]: This signal is the buffer overflow signal in Channelized
mode. If you do not respond to skip requests from the core in
Channelized mode, the internal per-channel buffer may overflow. In
that case, this signal is asserted during an active cycle on the
encryption egress side aligned with enc_egr_axis_tid[5:0]. When an
overflow occurs in Channelized mode, the corresponding channel must
be reset/flushed before being used again. Other bits are reserved. This signal must be ignored in Fixed Port mode. |
