Help: ICE_FLAGS_NCCLK

Normally, the 1st clock cycle is used to synchronize the enabling of a


Non-continuous clock - ports are enabled even if clock is not present.

Normally, the 1st clock cycle is used to synchronize the enabling of a
port. If the input clock is inactive when the transfer is enabled, the use 
of NCCLK will enable the master/slave/trigger signal without the clock.

Normally, output clocks are continuous once they are started in case there 
are PLLs on the receiving end.  If the receive device can handle a non-continuous
clock, this flags can be used to send bursty data from an output port.  The
SINKPIC throttle modes ONESHOT and ONDEMAND automatically add this flag.
