TX Sample Counter
The audio sample number of sending 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 valve at any time. After been updated by the initial value, the counter register should count on base of this initial value.
Note: It is used for Audio/Video Synchronization
