Hi,

I'm trying to program stm8s mic. but it's protected.

I marked unlock option in stm visual programmer and it didn't work.

What should I do for unlocking the mic ?

Thanks #programming-stm8s

Hi,

perhaps this helps: See

Reference manual [

STM8S microcontroller family]

(RM0016)

chapter 4.5 Memory protection

especially ch. 4.5.1 Readout protection: The readout protection can be disabled on the program memory, UBC, and DATA areas, by

reprogramming the ROP option byte in ICP mode.

In this case, the Flash program memory,

the DATA area and the option bytes are automatically erased

and the device can be

reprogrammed.
