You have to test yourself before anybody else will add it.

The each register read separately may take a long t= ime since EC is a separate uController that may be interrupted at any time by a= ny higher priority task (to be sure you have to have a look into the firmware source code). So, I'll be not surprised if 1s in some cases is not enough. = Not I'm against the shrtening the timeouts, but somebody should really know what they are about and why. --=20 You may reply to this email to add a comment.
