Hello guys, can I monitor interrupt0 of 8051 by any h/w means like by LED or something? I have connected RTC DS12887 IRQ to INT0 however I couldn't see logic 1 on DMM
Ok so I'll try putting XBYTE[0x0C] in my interrupt routine.
but I thought after servicing IRQ it would be ok no to read 0x0C
Even this routine doesn't trig ISR
