There are 8 subchannels that can be bound to an object using the 0x0000 method offset. The GCM userland driver sets them to following values:
| ID | Object | Handle | Name |

Remarks:
1. The *method offset* field consists of two fields: A 3-bit long *subchannel* identifier and a 11-bit long *offset* in that channel. At driver user-level, the whole 14-bit field can be considered as nothing but a 2-bit-rightshifted address where data goes in, optionally triggering an event. This notion is used on Nucleus for performance reasons.
1. The *method register* field consists of two fields: A 3-bit long *subchannel* identifier and a 11-bit long *offset* in that channel.

Method offset:
* `0x0000`: Binds the specified object to the *subchannel* specified in the method header.
* `0x0004`-`0x00FC`: Methods executed by the PFIFO puller, rather than being passed to execution engines.
* `0x0180`-`0x01FC`: Methods passed to execution engines translating the hash parameter to an instance via RAMHT.
