and then the result can be read from the
I2SDATH register.
Only one of the flags I2SCFG0.ULAWC and
I2SCFG0.ULAWE should be set to 1 when the
I2SCFG0.ENAB bit is 0.
13.15.13 I²S Registers
This section describes all the registers used for
I²S control and status. The I²S registers reside
in XDATA memory space in the region 0xDF40-
0xDF48. Table 33 on Page 49 gives an
overview of register addresses while the tables
in this section describe each register. Notice
that the reset values for the registers reflect a
configuration with 16-bit stereo samples and
44.1 kHz sample rate. The I²S is not enabled at
reset.

0
R/W µ-Law compression enable
0 Compression disabled
1 Compression enabled
ENAB=0 Enable compression of data received
ENAB=1 Compress data written to I2SDATH:I2SDATL
0
R/W TX mono enable
0 Stereo mode
1 Each sample of audio data will be repeated in both channels before a new
sample is fetched. This is to enable sending a mono signal to a stereo audio sink
device.
0
R/W RX mono enable
0 Stereo mode
1 Data from the right channel will be discarded, i.e. not be read into the data
registers. This feature is included because some mono devices repeat their
audio data in both channels and left is the default mono channel.
0
R/W Master mode enable
0 Slave (CLK and WS are read from the pads)
1 Master (generate the CLK and WS)
0
R/W I²S interface enable
0 Disable (I²S can be used as a µ-Law compression/expansion unit)
1 Enable
