Si5345 OTP can only be programmed two times, as different user configurations may required different setup
TE0808 is normally shipped with blank OTP.

This LED goes ON when power has been applied to the
module and
stays ON until MPSoC's programmable logic is
configured properly.

Si5345 OTP ROM is not programmed by default at delivery, so it is customers responsibility to either
configure Si5345 during FSBL or then use SiLabs programmer and program the OTP ROM with customer
fixed clock setup.
