the devices in the component. Only the manager is given
the ability to manage data channels in the system.
 No support for the elemental access mode for information
and value elements.
 No support for the following transport protocols.
▪ Asynchronous half-duplex
▪ Extended asynchronous half-duplex
 No support for the locked transport protocol.
 No support of a partial mask in CHANGE_VALUE message.
The maximum
clock output
slew rate might
be greater than
20% * VDD
[V/ns] for the
