After START_MEAS is set, TRIGG pin goes high and never falls. Isn't it supposed to just output a pulse?

I measure Vreg=1.6V.

Clock is 16MHz.

thanks

You mean with combined use with the tdc1000? I haven't gotten there yet, i just wanted to make sure tdc7200 worked first. TDC1000 works separately, producing the expected STOP pulses.

EDIT: I realized that in order for the TRIGG pin to go to 0 again, tdc7200 has to be connected to tdc1000. It works now.

thanks
