#111017 - IAP entering on P89V51RD2

More importantly, entering ISP mode seems to have been simplified which can only be a good thing.

Entering ISP on P89V51RD2 is very convenient as long as you are debugging it.
When you start using it in real environment, if there is a chance that there might be incoming characters while the chip is reset, you are in trouble.
Of course the bootloader can be modified, but there is no hint on it on Philips website. You need to find out the hard way, that it is identical with a SST chip and use their appnotes and datasheets...
