DESCRIPTIONS
-
Playback FIFO empty indicator bit
P_FIFO_EMPTY=0, the playback FIFO is not empty
P_FIFO_EMPTY=1, the playback FIFO is empty
The P_FIFO_EMPTY bit is read only
DMA end address interrupt request bit for playback
P_DMA_END_IRQ=0, means playback DMA address does not
reach the end address
P_DMA_END_IRQ=1, means playback DMA address reach the
end address
The P_DMA_END_IRQ bit is readable, and only can be clear
by write “1” to this bit
DMA address interrupt request bit for playback
P_DMA_MIDDLE_IRQ=0, means playback DMA address does
not reach the middle address
P_DMA_MIDDLE_IRQ=1, means playback DMA address reach
the middle address
The P_DMA_MIDDLE_IRQ bit is readable, and only can be
clear by write “1” to this bit
