Bit Descriptions:
The I
The I
for the data registers can be written without the I
clock cycles when writing to any of the control status registers.
When the I
this register.
The I
0. This will allow data be sent in a loop fashion from the transmitter back through the receiver.
This applies to all channels, with TX1 looped to RX1, and TX2 looped to RX2. When
loopback is active, data at the receiver input is ignored and transmit data is sent out normally.
The transmit section will control the clock configuration during loopback the same as if full-
duplex operation was used.

S global register deals with enabling the block and whether loopback mode is used.
S enable bit determines whether the PCLK is turned on for the I
S controller loopback mode bit determines if TX channel 0 is connected to RX channel
