SNAU309 October 2025 LMK3H2108
Figure 3-5 LMK3H2108 GPIO PageThe GPIO page contains the settings for configuring the GPI and GPIO pins of the LMK3H2108. Each GPI pin can have the input functionality disabled if not used. Each GPIO pin can have the input and output functionality disabled if not used. Each GPI and GPIO pin has pulldown and pullup resistors that can be individually enabled or disabled. Readback of the pin state is available for each GPI and GPIO pin.
GPIO pins, when configured as a status output, can provide a loss of signal status for each of the input clocks, or a clock ready signal when the device is ready to provide output clocks.
