Nowadays, i have some problem in Keyboard Interrupt function of MC9S08MP16.
The Port is PTD4/KBI3P4/PDB2OUT that is connected Hall effect sensor(open collector type).
also the Hall effect sensor input is connected to FTMCH1(to use as input capture function).
the problem is.
- Port value is changed in debug mode well.
- but, there's no KBI event.
( I already checked KBI Function by using push button switch so many times.
I confirm, KBI initialize and setup are no problem..)
- input capture interrupt is running well.
I wonder, Input capture interrupt well,,,,, but KBI no event?
I hope your advice..
Have a nice day~
