78 *Key file items are:-*
80      If this shows as enabled (1), but ``powered`` shows unpowered (0), then
81      the enable indicates a request to enabled when the device is powered.
82    * ``ctmid`` : associated CTM - only relevant if system has multiple CTI+CTM
84    * ``nr_trigger_cons`` : total connections - triggers<N> directories.
85    * ``powered`` : Read to determine if the CTI is currently powered.
87 *Sub-directories:-*
89    * ``channels``: Contains the channel API - CTI main programming interface.
101 CoreSight and non-CoreSight connections.

135 'regs' sub-directory elements directly.
