Suppose I have an IC that has a standard level triggered input pin. I need this pin's state to be setup immediately at power on at a time when my MCU's GPIOs may not have established levels. What are my options for accomplishing this while still being able to control the pin level at a later time?
My way that of course comes to mind is using a pull up/down resistor however that can have high leakage current. During the times my MCU is online I will have no use for the resistors as the pin state can be set by the MCU so this leakage is highly undesiable. Are there any options i'm not thinking of?
