Help: ICE_FLAGS_DEGLITCH
Enables deglitch circuit for MUXCLK inputs
Enables deglitch circuit for MUXCLK inputs. This is useful for digital
inputs with irregular clocks, such as from a switch matrix in scan mode
where the input clock may contain small ( < 4 nanosecond) glitches that
can cause unpredictable behavior in the IOC processor. This adds a
slight delay of approximately 5 nanoseconds to the input clock. For
clocks > 50MHz, the CLKDLY=N or CLKRE flags may be needed to clock the
data on a clean edge.
