I use LPC932 keypad:
when I set KBMASK=0x20 (enable p0.5 interrupt),it working ok!!
and I set KBMASK=0x80 (enable p0.7 interrupt),it also right!very good!
but when I KBMASK=0xa0 ( p0.5 and p0.7,enable ) lpc932 can't goto
interrupt vector address 003BH! because to my interrupt service program
can't run !
who can i tell me what something about me?my god!
