I am using some 12C508a's in internal RC mode, I jotted down the OSCCAL =
value before I erased it, but what is the proper way to put it back?

My best guess is  to add the following 2 lines and delete the 2nd when I =
get the bugs out and go to OTP parts.
 ORG     0x1FF=20
movlw 0x7C

I am just looking for verification that this is the way to do it.
