I just bought a PicStart Plus and Myke Predko's book about programming PICs.
I read his warning about the code protection bit so I made sure I didn't set
it.  I burned my first program into the 16C84 and then tried it on a proto
board.  I put it back on the PicStart Plus programmer and read the program
and then wrote it again.  When I read it however, I didn't notice that it
read the code protection bit as being "on". I was sure that it was off when
I read it the first time. I was using one of Myke's samples.  It turns out
that I now have the code protection bit on and I can't erase the PIC.  The
tech specs that were on the CD with the PicStart Plus give the following
blurb about turning the CodeProtection off.


4.1 Disabling Code-Protection
It is recommended that the following procedure be performed
before any other programming is attempted. It is also possible
to turn code protection off (code protect bit = 1) using this
procedure; however, all data within the program memory and the
data memory will be erased when this procedure is executed, and
thus, the security of the data or code is not compromised.
Procedure to disable code protect:
a) Execute load configuration (with a '1' in bit 4,code protect).
b) Increment to configuration word location (0x2007)
c) Execute command (000001)
d) Execute command (000111)
e) Execute 'Begin Programming' (001000)
f) Wait 10ms
g) Execute command (000001)
h) Execute command (000111)



I don't know how to do this.
Does anyone have a suggestion?
Thanks
