The initialization routine provides the hardware and software initialization of the COM2002x
registers, resets COM2002x, determines the Node ID, joins the network (participates in the
token passing scheme) and enables COM2002x for the reception of a packet. COM2002x
and the driver software are initialized according to the COM2002x Driver parameters (see
Section 4.5).
The D20 Driver parameters may be initialized by the d20_defaults() function or individually,
by the upper layers, using d20_set_parameter() function.
See Section 8 (an example program) for illustration of initializing the D20 Driver.

none
d20_init() returns the status of the initialization of the driver.
