3.1.2.3 Others

GUID-20230927-SS0I-FDH2-TCGN-HXVF102D2QX8-low.pngFigure 3-11 LMK3H0102 Others Page

The Others page allows for modification of remaining miscellaneous device fields. The ADC Divider is fixed at 153 - TI does not advise changing this value. The State Machine Clock Divider must be set so that the State Machine Frequency is as close as possible to 45 MHz. The polarity of the Output Enable Pin, as well as the behavior of the device when put into a disabled state, are both adjustable here. The Read Pin States button reads R10 from the device and populates the checkboxes below the button with the live pin states. The I2C configuration fields are used for configuring the I2C address - unlocking device in the User Controls page must be done prior to modifying these fields (User Controls → Customer: Controls, Pin setting, and Status → 0x5B to UNLOCK_PROTECTED_REG).

The Disable OTP Autoload checkbox disables loading of OTP Page 0 into the live device registers when the device comes out of a low power state. If changing the configuration of the device, this box must be checked to prevent the OTP autoload function, and can only be set while the Powerdown checkbox is checked. The Powerdown checkbox places the device into a low power state, within which the settings on the Section 3.1.2.1 and Section 3.1.2.2 pages can be modified. If the State Machine Clock Divider needs to change, then check this box, modify the divider, and clear this box. The Disable Pin Resampling checkbox, when cleared, allows for resampling of the device pins when coming out of a low power state. This can be used to transition from I2C mode to OTP mode by changing the state of the device pins, followed by toggling the Powerdown checkbox from cleared → checked → cleared. Transitioning from OTP mode back to I2C mode requires a power cycle of the device.
