stm8s illegal wakeup from halt.

[Wonjeong]

I'm working on with STM8s105k4.
The problem is illegal wakeup from halt mode after about 8us itself.
There are any condition is nothing to wake from halt mode.
External interrupts are all disable. there is no any interrupt.
all Comm modules are off state.
WDT is not used also(not is started)
I don't know why it is doing almost free pass from halt instructin.
How do I fegure it out. I have no idea.

Please help me ㅜㅜ

Hello @Wonjeong 

I think this errata maybe the source of the problem.

You can find it with other stm8s105 in the ES0110.

Best regards.
