GPIO Sense Power Consumption?

Question

I have searched here for an answer to this, but cannot find exactly what I am looking for. I am trying to put my Rev3 51822 to sleep and wakeup via GPIO. When I enable GPIO sense, power consumption is increased at least five times. Is this expected? I have tried various drive settings on this line and cannot get the power any lower.

I have seen some mention of higher current consumption, but it is not clear to me if the GPIO sense has a higher current draw. What alternative is there?

This line causes the custom board to consume about 10.5 mW.

	NRF_GPIO->PIN_CNF[27] = (GPIO_PIN_CNF_SENSE_High << GPIO_PIN_CNF_SENSE_Pos)
									| (GPIO_PIN_CNF_DRIVE_D0S1 << GPIO_PIN_CNF_DRIVE_Pos)
									| (GPIO_PIN_CNF_PULL_Pulldown << GPIO_PIN_CNF_PULL_Pos)
									| (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos)
									| (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);

If I turn GPIO sense off, the board power consumption is down to 2.64 mW, which is acceptable. This is approximately 200 microamps from 12V.

	 NRF_GPIO->PIN_CNF[27] = (GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos)
                                    | (GPIO_PIN_CNF_DRIVE_D0S1 << GPIO_PIN_CNF_DRIVE_Pos)
                                    | (GPIO_PIN_CNF_PULL_Disabled << GPIO_PIN_CNF_PULL_Pos)
                                    | (GPIO_PIN_CNF_INPUT_Disconnect << GPIO_PIN_CNF_INPUT_Pos)
                                    | (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);
