Play/Record Data
The play/record interrupt will be activated when play/record data is valid on PLAY_DATA/ RECORD_DATA registers.
The PLAY_DATA/RECORD_DATA registers will latch data until next interrupt happen. The PLAY_DATA is unsigned
value (0~FFFFH). RECORD_DATA is 2 s complement value (8000H~7FFFH).
The update rate of RECORD_DATA is 8kHz . The update rate of PLAY_DATA is 48kHz (PLAY_MODE=0) or 8KHz
(PLAY_MODE=1). All these registers (3AH~3FH) are read only.
