/* Test to see if clocks are
/* actually there. Because the SBC
/* after reset does not deactivate
/* its clocks immediately we will
/* make pretty sure that the clocks */
/* are there before we leave this
/* routine
/* we test to see if 6 changes in
/* the STAR:BVS bit indicating the
/* reception of at least 3 frames
/* (6 B channels). If at any time
/* we fail to find a bit change
/* and the counter i reaches its
/* maximum then we assume that
/* clocks are no longer present
/* Of course we have to reset our
/* counter every time a bit change
/* is observed to give the next
/* bit change the same amount of
/* time in which to occur !!!
/* the Bx versions reqire one edge
/* at FSC.
/* Otherwise the setting of the SPU */
/* has no effect (result: no clock) */
/* The IOM direction control bit
/* IDC in the ADF1 (SQXR) register
/* is set before and reset after
/* the system is clocking
