the Touch Probe 1 function is triggered by the external DI. When OD 60B8h [Bit 1]
is set to 0 and OD 60B8h [Bit 4] & [Bit 5] are set to 1, the Touch Probe 1 signal is
both rising-edge and falling-edge triggered, and the data is captured once for each
triggering.

Enable Touch Probe 1.
Capture one time.
Start capturing when the Touch Probe 1 signal is
rising-edge triggered.
Start capturing when the Touch Probe 1 signal is
falling-edge triggered.
Touch Probe status: Touch Probe 1 function enabled.
Touch Probe 1 is rising-edge triggered by external signal.
Touch Probe status: Touch Probe 1 is rising-edge
triggered and the data is successfully captured.
Store the captured data in OD 60BAh when the Touch
Probe 1 signal is rising-edge triggered.
Touch Probe 1 is falling-edge triggered by external
signal.
Touch Probe status: Touch Probe 1 signal is
falling-edge triggered and the data is successfully
captured.
Store the captured data in OD 60BBh when the Touch
Probe 1 signal is falling-edge triggered.
Disable the rising-edge trigger action of Touch Probe 1.
Touch Probe status: reset the rising-edge capture
status to non-triggered.
Data at the rising-edge remains the same.
Start capturing when the Touch Probe 1 signal is
rising-edge triggered.
