MER
/POT0
Bit 0 (/POT0): program ROM protect option.
If set 1 to the bit, program memory can be access; else if clear this bit , program memory can not be
access.
Bit 3(MER) : Memory error recover function
0 Î disable memory error recover function
1 Î enable memory error recovery function
If user enable memory error recovery function, MCU will improve effect from environment noise.
Bit 9: Please set this bit to 1.
Bit 10: Please clear this bit to 0.
Bit 11: Please clear this bit to 0.
