Detailed Description

Definition of the commands supported by the OpenULINK firmware.

Basically, two types of commands can be distinguished:

Commands with fixed payload size
Commands with variable payload size

SCAN commands (in all variations) carry payloads of variable size, all other commands carry payloads of fixed size.

In the case of SCAN commands, the payload size (n) is calculated by dividing the scan_size_bits variable by 8, rounding up the result.

Offset zero always contains the command ID.
