Hi:
8.4.3 Timeout
For one STOP, the TDC performs the measurement by counting from the START signal to the STOP signal. If no
STOP signal is received, either the Clock Counter or Coarse Counter will overflow and will generate an interrupt
(see Coarse and Clock Counters Overflow). If no START signal is received, the timer waits indefinitely for a
START signal to arrive.
My questions are as below:
1. when the Clock Counter or Coarse Counter overflow, will the signal at pin INTB go low?
2. When the overflow happens, the TDC7200 will start the next new measurement automatically? or should we set the STAR_MEAS to be 1 through the SPI to start the new measurement? I
3. I know when the measurement is completed successfully, the INTB will go low and is easy for the MCU to detect the status. If the overflow can't pull down the signal at pin INTB, then it will be difficult to decide when to start a new measurement which was halted by overflow, because it's impossible for the MCU to poll the INT_STATUS register frequently.
Thanks
Zhang
