did you desolder it or are you trying to write it with a clip?

I have never had any problem using cheap EZP2000 or tl866 programmer

Check protection flags

Two flag bits are used to indicate the Protection
Register status:
– Protection Flag: this is used to enable/disable
protection of the write-protected area of the
M93Sx6 memory
– OTP bit: when set, this disables access to the
Protection Register, and thus prevents any
further modifications to the value in the
Protection Register.
