ALL CMD queues must be terminated with either END or STOP.
If END is used, when refilling the cmd[] next time, no entries from END to [15] can be used.
AND the cmd[] must be filled starting at [0] with commands. Either fill all 15 [0]..[14] and leave the
END in [15] or include a STOP in one of the positions [0]..[14]. Any entries after a STOP are IGNORED byte the StateMachine.
The END operation does not complete until ctr->trans_start=1 has been issued.
So, only refill from [0]..[14], leave [15] for a continuation if necessary.
As a corrilary, once END exists in [15], you do not need to overwrite it for the
next continuation. It is never modified. But, I update it every time because it might
actually be the first time!
23NOV17 START cannot proceed END. if START is in[14], END cannot be in [15].
so, AND if END is moved to [14], [14] and [15] can nolonger be use for anything other than END.
If a START is found in [14] then a prior READ or WRITE must be expanded so that there is no START element in [14].

Need to think about not usings I2C_MASTER_TRAN_COMP_INT_ST to adjust queuePos. This
INT triggers every byte. The only reason to know which byte is being transfered is
the status_reg.tx_fifo_cnt and a .txQueued to do this in the fillRxFifo(). The
same mechanism could work if an error occured in i2cErrorExit().
