I said:
When I use my parallel programmer (Needhams EMP-11) I can't access the 2K byte eeprom (although I can access a 64 byte area called the User Row). So how on earth can I program it - or can I only do that programatically? Correction - I can access it by editing the buffer. It appears in memory above the code space starting at 3000h. Code memory ends at 2FFFh I said:
Is the User Row part of the eeprom? Apparently not, but I still don't know what it is. I said:
Is it just my programmer that won't read the eeprom, or any programmer? Scratch that. I said:
If I set the lock bits does it also prevent the eeprom being read by a programmer as well as the rom? Don't know yet, but I know where to look. |
