Hi Raghu (All),

Thanks for the quick reply, (Thanks everybody). Well actually I am using ATMEL's 8052 Variant running at 40 Mhz. There is no specific application in my mind. It will be general purpose test board. With 64 + 64 Digital I/O, 16 + 16 Analog I/O, (16 Key) Keypad (optional), 16X2 LCD Module (optional)

So far its all in design phase. Well the idea of using Switch-Debouncers is good one but i have to verify the COST, Also One solution provided by Mr. Alfredo del Rio is also good alternative. As its a General Purpose test project. Response may not be the at highest priority, still we shuld know alternatives so that we can best utilize resources we have,

Well thanks a lot to all,

with regards
