This register is used to read transmit PCM data via the MCU interface. Reading this register the IPCM interrupt
(if generated only by reading access) is automatically cleared.
In A/µ law only the first 8 bit are used. In linear code option both registers must be read, first the LSB and after
the MSB.

POW
PMW
PMW = 1: Data is not written every FS while writing PCM access data is enabled.
POW = 1: Data is not read every FS while reading PCM access data is enabled.
WRD = 1: Device is waiting for PCM data insertion in PCMWD register. The bit is reset after writing at least one byte.
RRD = 1: Data are available on PCMRD register. The bit is reset after reading the two bytes of the register (first
the LSB and after the MSB).

Tn0=0,Tn1=0: No tone is generated on ch #n
Tn0=1,Tn1=0: A tone with 25Hz frequency is generated on ch #n.
Tn0=0,Tn1=1: A tone with 1KHz frequency is generated on ch #n.
Tn0=1,Tn1=1: A tone with 3KHz frequency is generated on ch #n.
This register allows the generation of a tone in the RX direction.
