Reset (RST) and Release (REL) Control Signals
R
RST and REL are the control signals for the PMCD. The interaction between RST, REL, and
the PMCD input clocks help manage the starting and stopping of PMCD outputs.
The reset (RST) signal affects the PMCD clock outputs in the following manner:
•
•
•
Asserting RST asynchronously forces all outputs Low.
Deasserting RST synchronously allows all outputs to toggle:
♦
♦
♦
By setting the RST_DEASSERT_CLK attribute, deasserting RST can be synchronized
to any of the four input clocks. The default value of RST_DEASSERT_CLK is CLKA
(see
The delayed outputs begin toggling one cycle after RST is deasserted and is
registered.
If EN_REL = FALSE (default), the divided outputs will also begin toggling one
cycle after RST is deasserted and is registered.
If EN_REL = TRUE, then a positive edge on REL starts the divided outputs
toggling on the next positive edge of CLKA.
