  TX_CNT

TX Sample Counter
This is the audio sample number that sent into TXFIFO.
When one sample is put into TXFIFO by DMA or by host IO, the TX sample
counter register increases by one. The TX sample counter register can be
set to any initial value at any time. After updated by the initial value,
the counter register should count on base of this initial value.
