Hi everybody, I'm new to this forum!
Currently I'm using AT89C51 (plain) but need to
switch to the AT89C51RC2 for greater speed.
I've read the docs on RC2,
but some things aren't quite clear:
1. can the RC2 be programmed the same way (parallel)
as the AT89C51? If not, what should I change in
the programmer PCB/software?
2. is it true that, after flashing the RC2 using parallel
method and setting the lock bits to 3, the unit cannot be
read with parallel method but can still be read with the isp method
and that I must use both methods if the security is important?
Thank you
