The problem regarding ATMEL 89C2051 which I would like to put forward
can be explained as follows -

Programs such as a simple logical type which is well running in simulated
environment and also on 2051 MCU but sometimes god knows why the MCU
is getting locked & the MCU is getting heated tremendously. Reset is unable
to bring the MCU out of that situation. Only power reset is able to bring the MCU out of the situation.

I have tried at least 4 different MCUs. Nothing is different.

Can any friend help me in solving the problem ?
