Now spaces in the program memory of all MCUs, including mcs51, are filled with 0xFF.

But mcs51 should use 0x00(NOP) to fill them.

See:

"NOP is typically used to generate a delay in execution or to ***reserve space in code memory****."

As far as I know most non volatile memories have bit value = 1 when erased.
