3.1.1.4 OTP Options

GUID-20230428-SS0I-LKD1-XC5Q-C6HSNZNX11QN-low.pngFigure 3-5 LMK3H0102 Wizard OTP Options Page

The OTP Options page allows for configuration of the additional OTP pages that are not present in the live registers. If using the wizard in I2C Mode, then this page is skipped by default, and the options on the page are greyed out if the page is manually navigated to. The format of the output clocks, the output enables, and the SSC on FOD0 can all be modified across the different OTP pages. The Page 0 settings are specified based on the prior wizard pages. Changing the page 0 fields requires navigating to the previous pages.

The OTP Identification and I2C Address fields are all shared between the four OTP pages. OTP Identification is a four-bit field that can be set to any integer value between 0 and 15. The I2C Address is a 7-bit field that can be set to any value between 0 and 127 allowed by the I2C standard. The two least significant bits of the I2C address are set by the state of the FMT_ADDR pin on start-up.

When in the I2C + OTP Configuration mode, the block diagram on the OTP Options and Review pages has a dropdown that allows for showing the pin configuration for the specified OTP page.
