Hardware Trigger Application:
Step1: Set Enable_Position_Compare (0x7000:0B) to "1".
Step2: When a pulse input to the AMAX-5081 Latch pin, the current counter value will
be updated to Latch_Value (0x6000:12).
Step3: Wait until the Counter_Value (0x6000:11) ≥ Latch_Value (0x6000:12) +
Set_Position_Compare_Offset_Value (0x7000:12), the AMAX-5081 Pulse_Output
pin will output a pre-defined width of pulse and the Enable_Position_Compare_ Done
(0x6000:07) will be raise to "1".
Step4: After the pulse output is done, set Enable_Position_Compare (0x7000:0B) to
"0"
Step5: Check if Enable_Position_Compare_ Done (0x6000:07) is changed to "0"
coordinately, and back to step1 for the next compare trigger signal.
