C251: HOW COMPATIBLE IS THE 251 WITH THE 8051?
QUESTION
How compatible is the 251 with the 8051?
ANSWER
The 8xC251SB is 100% compatible with the 80C51Fx parts from Intel. Simply set the 251's configuration bytes for binary mode as follows:
Config0 = 0xDE Config1 = 0xE7
and your 251 microcontroller runs all of your existing 8051 code with NO changes.
