 		 #90989 - Philips's angwer
Responding to: ???'s previous message
Question:
How to program the boot vector ?
Where can i find any documentation about the 87c51 like interface but not exactly, and what means not exactly ? how not exactly ? And what is the command set ?

Philips Semiconductors answer:
Thank you for your interest in Philips Semiconductors!

The boot vector can be programed via IAP or ISP (using Flash MAgic from www.esacademy.com), or via a parallel programmer (usually via a pull down options menu).

The 89C51Rx2 family is fully compatible with the 87C51 except it has more on chip RAM. The command set is the same for both devices.


Does this means that it can be programmed in 87c51 parallel programmer ???
