Dear, All
I ask about "Measurement edge" of TDC7201.
I want to know the following sentences in P19 of the data sheet.
"For highest measurement accuracy in measurement mode 2, TI recommends to choose for the START and STOP signal the rising edge. This is done by setting the START_EDGE and STOP_EDGE bits in the TDCx_CONFIG1 register to 0 ".
The reason why a choice has good precision wants to know rising ede.
The customer thinks about the following direction for uses.
・ They choose rising ede in Start and stop together in TDC1.
・ TDC2 chooses rising ede in Start, and the stop chooses falling edge.
・ They calculate stop pulse width with differences between TDC1 and TDC2.
In this case does precision of the stop pulse width not appear?
Thanks, Masami M.
