When the ROM code protection is active by the ROMCP1 bit setting, the flash memory is protected against reading or
rew riting in parallel I/O mode.
Set the bit 5 to bit 0 to “111111b” w hen the ROMCP1 bit is set to a value other than “11b”.
If the bit 5 to bit 0 are set to values other than “111111b”, the ROM code protection may not become active by setting
the ROMCP1 bit to a value other than “11b”.
To make the ROM code protection inactive, erase a block including the ROMCP address in standard serial I/O mode
or CPU rew rite mode.
The ROMCP address is set to “FFh” w hen a block, including the ROMCP address, is erased.
When a value of the ROMCP address is “00h” or “FFh”, the ROM code protect function is disabled.
