TDC LEDs
++++++++
There are 6 orange LEDs on the front panel of each TDC board.
* LED STA blinks upon a "local PPS pulse".
* LED#1 blinks upon the writing in the "circular buffer" of a timestamp
referred to channel 1.
If the input termination for channel 1 is ON, there is a blinking when
the timestamp is written; if the input termination is OFF, the LED is
always ON and it turns OFF when the timestamp is written.
* LED#2..LED#5 function accordingly for channels 2..5. The signals regarding
the channel number and the writing in the "circular buffer" come from
the "data formatting" unit.
