 		 #67277 - RE: 8 External interrupt in 51 controller
Responding to: ???'s previous message
<html>
the standard 8051 support already 5 interrupt sources

Right, EXT0, EXT1, SERIAL, T0, T1

which all can be triggered from external signals.

All interrupts aren't alike and cann't be used to handle devices requiring interrupts only EXT0, EXT1 can be hooked to such devices.
Serial, T/C0, T/C1 are for serial communication and timer/counters and can'nt be used as General Purpose Interrupts.
