The STM8T143 can be configured through a set of user-selectable one-time programmable
(OTP) option bytes. These options can be used in their default (unconfigured) state or set for
specific applications. For large orders, preconfigured devices are available (please refer to

Option byte description
A set of tools is supplied by STMicroelectronics to program the user OTP options for
prototyping purposes. Please refer to
details.
Devices which are not yet programmed (also called blank devices) are delivered with all bits
set to ‘0’.
