LP-MSPM0L1117: the power consumption becomes high when I use DL_GPIO_initDigitalInputFeatures?

Part Number: LP-MSPM0L1117


hi,

originally, the power consumption is ~2uA on EVM.

when I use below for PA6 and set DL_GPIO_enableHiZ(GPIO_GRP_0_PIN_6_IOMUX), the power consumption becomes ~110uA.

    DL_GPIO_initDigitalInputFeatures(GPIO_GRP_0_PIN_6_IOMUX,
         DL_GPIO_INVERSION_DISABLE, DL_GPIO_RESISTOR_NONE,
         DL_GPIO_HYSTERESIS_DISABLE, DL_GPIO_WAKEUP_DISABLE);
 
Any idea, how can I achieve low power after i don't want to use the pins?
By the way, not every pins have this issue. some pins have higher power consumption some pins have lower power consumption.
 
BR,
