Dear:

We use two TDC7200 to get TOF time,I will get low signal from TDC_INT pin as below picture,

But I don't know which TDC7200 INT pin to low? why does TDC_RX_INT pin "and " TDC_TX_INT pin with SN74LVC1G08?

when TDC_INT pin gets low I don't know which 7200 is ready for result.

Hello,

After the last STOP trigger has been received, the TDC will signal to the MCU via interrupt (INTB pin) that there are new measurement results waiting in the registers.

INTB and so the output of the SN74LVC1G08 will go low every time there is a new measurement results waiting in the registers of each TDC.

Let me know if you have additional questions.

Best regards

Giovanni
