2.4.9.1. Enhanced PCS TX and RX Control Ports
This section describes the tx_control and rx_control bit encodings for different
protocol configurations.
When Enable simplified data interface is ON, all of the unused ports shown in the
tables below, appear as a separate port. For example: It appears as
unused_tx_control/ unused_rx_control port.
Enhanced PCS TX Control Port Bit Encodings
Table 58. Bit Encodings for Interlaken
Name Bit Functionality Description
tx_control
[1:0] Synchronous header The value 2'b01 indicates a data word. The value
2'b10 indicates a control word.
[2] Inversion control A logic low indicates that the built-in disparity
generator block in the Enhanced PCS maintains
the Interlaken running disparity.
[7:3] Unused
[8] Insert synchronous header error or
CRC32
You can use this bit to insert synchronous header
error or CRC32 errors. The functionality is similar
to tx_err_ins. Refer to tx_err_ins signal
description for more details.
[17:9] Unused
