take effect. Changes take effect when a session on a newly configured interface
is started for the first time within a process.
Care should be taken when a running application is using the TAMS GPIO
interface while it is reconfigured.
If, for example, a polarity setting is changed on an interface while an application
is using it, it may take effect in the middle of a transfer causing undesired effects.
However, no fatal effects such as a system crash or device hang will be caused.
It is safest to perform an
iclear
on the interface after modifying its
configuration to guarantee that it is in a known state.
