Abstract
A FIFO queue is utilized to provide control information to the appropriate time slot in a time multiplexed serial link between an interface chip and a CODEC. The FIFO queue allows rewriting or replacement of any control registers present in the queue without requiring that a new entry be placed in the queue. A particular control register which is placed in the queue then maintains its place as the queue is emptied, even though the control register may be written one or more times while the control register entry is in the queue waiting for transmission to the CODEC. The loss of the prior command information is not a problem as the data rate of the serial link is still sufficiently high so that any minor transitory change which may have been desired would be of minimal effect in any regard and would have been inaudible to the human.
