 		 #119766 - That's my case!
Responding to: ???'s previous message
Erik said "I have never used KBI, it serves no purpose except in cases where you need a keypress to wake the processor up."

That is my case here:
I need to wake up the mcu from an outside Switch (momentary). I am already using the INT0, INT1 and one KBI pin. So I thought I could use another KBI pin. I cannot use any other pins mentioned above in this case. I am going to try your suggestion.
"This MAY be correct operation of the chip. Disable the KBI in the ISR and reenable it when you, no, the chip :) go to sleep. "

My case is a interrupt, which never occurs.

Thank you

Caleno

LPC932 KBI Interrupt            01/01/70 00:00      
   nothing to do with KBI            01/01/70 00:00      
   Port is good!            01/01/70 00:00      
      whay do you not do as suggested?            01/01/70 00:00      
         I did it            01/01/70 00:00      
            below you talk about a 'stuck' interrupt            01/01/70 00:00      
   More details.            01/01/70 00:00      
      I have never used KBI, it serves no purp            01/01/70 00:00      
         That's my case!            01/01/70 00:00      
            you posted that interrupt DOES occur:            01/01/70 00:00      
               Do not get confused            01/01/70 00:00      
                  continuing            01/01/70 00:00      
                     EA is set            01/01/70 00:00      
                        so, you have an ICE, great            01/01/70 00:00      
                           ICE could affect KBI            01/01/70 00:00      
                              How is your P0 set up            01/01/70 00:00      
                                 forget it            01/01/70 00:00      
                                    ICE?            01/01/70 00:00      
                                       In Circuit Emulator            01/01/70 00:00      
                                          ICE            01/01/70 00:00      
                                             maybe it is ( to some extent?)            01/01/70 00:00      
                                                Yes            01/01/70 00:00      
                                                   Ok an emulator, (E) not an ICE            01/01/70 00:00      
                              as usual - divide and conquer            01/01/70 00:00      
                           Back on track            01/01/70 00:00      
                              you need to change something in the ISR            01/01/70 00:00      
                                 I Got it!            01/01/70 00:00      
         Does this help            01/01/70 00:00
