(A) Continuously checking some X-ray radiation with monitoring the data of trigger photodiode by an external circuit.
(B) The MST should be set at low and integration of each pixel is to start when X-ray input is detected.
The Integration time is almost same as the low width of the MST. It can be controlled by an external circuit
(software, firmware, etc.).
(C) Just after the MST is set at high, the integration is to finish and readout starts.
(D) Each readout row has a header part, which consists of 28 high levels of the OUTDATA.
(E), (F) After completion readout, the OUTCLK and the OUTDATA automatically move to state of trigger photodiode
