In non-bonded mode, separate CGBs are used for each channel and the skew between
channels is not carefully controlled.
The reset controller generates a reset sequence appropriate for the protocol. Using the
reset controller section of the memory map, you can choose have the reset sequence
apply to all channels (the default behavior), or mask out some channels so that those
channels will not be affected by the reset sequence. For bonded modes, you should
allow the reset sequence to affect all channels.
The reset controller drives the following reset signals:
■

■
rx_analogreset—This signal resets the analog CDR and deserializer logic present
in the RX channel. (CDR is the first step of the power-up process.)
rx_digitalreset—This signal resets all digital logic in the RX PCS and PMA.
tx_digitalreset—This signal resets all logic in the TX PCS.
