Hello,

I tried to flash a PIC12F509 but in the loaded file display, the addressing stops at 0x3FE.
Checking the file with an HEX editor the last byte 0x3FF is available, so the file is good.

Any idea how to solve this?
The last byte is never written...

Regards, Msmax

PS. Why the whole site is in Chinese while I selected English?

Compare with 12C509:

12C509: IC Size 0x400 Words (2048 bytes)
12F509: IC Size 0x3FF Words (2046 bytes) ???

Both is the same size....

Forget it... the last byte contains the Internal RC Oscillator calibration value and should never be overwritten.
The software just takes care of that...
