| R0 | 2 (reason code) |

Use
This vector is called by the Kernel when a pointer device type is selected with OS_Pointer.
Notes
A device driver should enable itself if it supports this device type, otherwise disable itself.
The call must not be intercepted.
This particular reason code is only available from RISC OS 3.5 onwards.
