Description
Left-Channel Receive Data
These bits store data received from the SIOF_RXD pin
as left-channel data. The position of the left-channel
data in the receive frame depends on the value set in
the RDLA bit in SIRDAR.
•
Right-Channel Receive Data
These bits store data received from the SIOF_RXD pin
as right-channel data. The position of the right-channel
data in the receive frame depends on the value set in
the RDRA bit in SIRDAR.
