GPIO_0.GPIO_DCO_INC_DEC
Increment/decrement DCO FFO configuration. Applies when GPIO_FUNCTION is equal to 'inc DCO FFO' or 'dec DCO FFO'. The squelch
level is determined by the configuration per output by OUTPUT_n.OUT_CTR_1.SQUELCH_VALUE.
GPIO_0.GPIO_OUT_CTRL_0
Define the set of outputs to be squelched by this GPIO input. Applies when GPIO_FUNCTION is equal to 'clock output control'. The squelch
level is determined by OUTPUT_n.OUT_CTRL_1.SQUELCH_VALUE.
