Bit 5:4 I2SSTD: I2S standard selection
Bit 2:1 DATLEN: Data length to be transferred
Bit 7 PCMSYNC: PCM frame synchronization
Bit 6 Reserved: forced at 0 by hardware
Bit 3 CKPOL: Steady state clock polarity
Bit 0 CHLEN: Channel length (number of bits per audio channel)
Note: This bit has a meaning only if I2SSTD = 11 (PCM standard is used)

0: Short frame synchronization
1: Long frame synchronization
00: I
01: MSB justified standard (left justified)
10: LSB justified standard (right justified)
11: PCM standard
0: I
1: I
00: 16-bit data length
01: 24-bit data length
10: 32-bit data length
11: Not allowed
0: 16-bit wide
1: 32-bit wide
The bit write operation has a meaning only if DATLEN = 00 otherwise the channel length is fixed to
32-bit by hardware whatever the value filled in.
