System frame pulse for transmitter section.
Line frame pulse for receiver section.
System clock (sys_clk). This signal is routed onto a primary clock net inside the
FPGA, with very low skew.
STM channel protection enable for channels aa and ab. Active-high.
STM channel protection enable for channels ac and ac. Active-high.
STM channel protection enable for channels ba and bb. Active-high.
STM channel protection enable for channels bc and bd. Active-high.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
LVDS buffer redundancy select for rx channel aa. Active-high for redundant link.
During powerup and FPGA configuration sequence, the core_ready is held low. At
the end of FPGA configuration, the core_ready will be held low for six clock
(sys_clk) cycles and then go active-high. Flag indicates that the embedded core is
out of its reset state.
