8.2.3 CONTINUOUS Measurement Mode
If a trigger signal input from EXT I/O or by touching on the screen in CONTINUOUS measurement
mode, the judgment results will be output from the signal lines of EXT I/O comparator result output
after measurement of all panel No.’s set to be executed on the screen.
The following are examples for the measurement timing.
In the timing example, the valid edge of the TRIG signal is set to falling (ON).
Example: Continuous measurement using panel No. 1, 2, and 4

For both INDEX and EOM, transition to HIGH is performed when the first panel measurement
