Check the pll_powerdown signal. This signal allows you to power down the
CMU PLL. Use this signal as part of your reset sequence.
Check the pll_locked signal. This signal indicates whether the CMU PLL is
locked to the input reference clock. The user logic waits until the pll_locked
signal goes high before transmitting data.
Check the rx_freqlocked signal. This signal indicates whether the receiver
CDR is locked to data. When the receiver CDR is configured in automatic lock
mode, assert the rx_digitalreset signal if the rx_freqlocked signal goes low
to keep the receiver PCS under reset. Altera recommends specific transceiver
reset sequences to ensure proper device operation.
