Example 1: the following is the timing diagram for the Touch Probe 1 function. In this example,
the Touch Probe 1 function is triggered by the external DI. When OD 60B8h Bit 4 is enabled,
the data is captured once whenever the Touch Probe 1 signal is rising-edge or falling-edge
triggered.

Status Function Description
(1)
OD 60B8h Bit 0 = 1 Enable Touch Probe 1.
OD 60B8h Bit 1 = 0 Capture one time.
OD 60B8h Bit 4 = 1
Start capturing when the Touch Probe 1 signal is
rising-edge triggered.
OD 60B8h Bit 5 = 1
Start capturing when the Touch Probe 1 signal is
falling-edge triggered.
(2) OD 60B9h Bit 0 = 1 Touch Probe status: Touch Probe 1 function enabled.
(3) - Touch Probe 1 is rising-edge triggered by external signal.
(4) OD 60B9h Bit 1 = 1
Touch Probe status: Touch Probe 1 is rising-edge
triggered and the data is successfully captured.
(4a) OD 60BAh
Store the captured data in OD 60BAh when the Touch
Probe 1 signal is rising-edge triggered.
(5) -
Touch Probe 1 is falling-edge triggered by external
signal.
(6) OD 60B9h Bit 2 = 1
Touch Probe status: Touch Probe 1 signal is
falling-edge triggered and the data is successfully
captured.
(6a) OD 60BBh
Store the captured data in OD 60BBh when the Touch
Probe 1 signal is falling-edge triggered.
(7) OD 60B8h Bit 4 = 0
Disable the capturing when Touch Probe 1 signal is
rising-edge triggered.
(8) OD 60B9h Bit 1 = 0
Touch Probe status: reset the rising-edge triggered
status to non-triggered.
(8a) OD 60BAh Data at the rising-edge remains the same.
(9) OD 60B8h Bit 4 = 1
Start capturing when the Touch Probe 1 signal is
rising-edge triggered.
