Capture T5 question in XC2000
Hello when I use “GPT2 Capture/Reload Register CAPREL in Capture-And-Reload Mode” Function in XC2000,I set as follows
1) T5 Count Up
2) Any edge change of T3IN and T3EUD(Motor Hall Sensor Input) Trigger Capture T5 into CAPREL,and Clear T5 .

But when I Draw the value of “CAPREL”, It looks like CAPREL is equal to ZERO sometimes.Why Is that? Is Any spike input from T3IN and T3EUD,or any other reason?

this Problem has been solved ,because the high level of T3In and T3EUD is 3.3v and the rising time is too long (nearly 20us),
when I cancel the Cap bypass,and Set input level as 5V,the Capture value of T5 never show Zero.
