4 Contact: devel@lists.laptop.org
7 A generic interface for executing OLPC Embedded Controller commands and
8 reading their responses.
10 To execute a command, write data with the format: CC:N A A A A
11 CC is the (hex) command, N is the count of expected reply bytes, and A A A A
12 are optional (hex) arguments.
14 To read the response (if any), read from the generic node after executing
15 a command. Hex reply bytes will be returned, *whether or not* they came from
16 the immediately previous command.
