Help: ICE_FLAGS_OKNC
Turn off clock loss detect circuit.
Turn off clock loss detect circuit.
This flag is useful in applications where the timecode NoClock error status
is bogus or otherwise ignorable. This flag causes pic_tc() to replace the
status with a TC_OKNC status. This flags the noClock problem but is still
a positive value indicating an OK timecode value.
Examples: Using SINKPIC/throttle=2 to play back intermittently sets the
sample rate to 10e3 triggering the noClock bit. But this is OK.
NOTE: The IOC has a clock loss circuit for input data rates > 200kHz. If
no clocks are detected over a 5usec period, it is assumed that the clock,
even if it recovers, may have had glitches that would render the timecode
values invalid. If this occurs, PIC_TC will return a -7 status until the
acquisition is restarted. The OKNC flag turns this status into a TC_OKNC
status which recognizes the timecode as good, assuming the noClock is bogus.
