4.6.1. How to Read the Real-Time Lock Status of the FGT TX PLL

Sice the tx_pll_locked sigal fo the FGT TX PLL povides eithe a sticky idicatio of the PLL’s lock state, o i the pesece of a efeece clock, afte appoximately 150 µs, it is ecessay to use the ecofig_xcv Avalo® Memoy-Mapped bus i ode to obtai a eal-time idicatio of the lock state of the TX PLL. I ode to ead the eal-time lock state of the TX PLL, ead locatios o the ecofig_xcv Avalo® Memoy-Mapped bus as show i the followig table. The locatio is chael-specific withi the Quad ad the addess offset is subject to the ules outlied i sectio Cofiguatio Registes . A value of 1’b1 idicates that the TX PLL is locked to the efeece clock.
