Hi,
       Can anyone guide me how to recover back to isp mode if you accidentally erased LPC936?

Thanks,
pak

any chip, whatever is erased, can be programmed in a parallel programmer.

the chips are not that expensive (digikey $2), if you do not have, or know someone with, a parallel programmer, just buy a new chip.  Of course, if you have done it to a bunch of chips, buying a parallel programmer (stay away fro Xeltek) may be the better choice.

Hi Erik,
        Thank for reply, Do you have any suggestion to avoid corruption of ISP on LPC9xx? I did not touch ISP check box but it still has connection problem. My board is MCB900 and LPC936. Please guide some factors these can corrupt ISP?

Thanks,
