length) or a long (word length) frame sync, which is selected
by the VCELONGFS bit. The frame sync can also be inverted
by setting the VCEFSINV bit.
and Rx. The active slots used by the voice CODEC are
controlled by the VCETXSLOT[1:0] and VCERXSLOT [1:0]
bits. The short frame sync occurs 1 bit clock cycle before the
data MSB, whereas the long frame sync is aligned with the
MSB. For multiple time slots, an optional turn around time
delay of 1 bit clock cycle can be added in between the slots
by setting the VCETRNARND bit. Outside of the assigned
