#98994 - but ALE is "just" ALE, not a GPIO, pleas Responding to: ???'s previous message |
BY freeing ALE i want to use it for RAM powerdown and power switching.
but ALE is "just" ALE, not a GPIO, please show how you propose to use ALE for the above purpose, NVRAM powerdown comes up quite often and if you have a dynamite way to handle it do show us. Erik |
