Word Select Receive (WSR)—WSR is an output if the
receiver section is configured as a master, and a
Schmitt-trigger input if configured as a slave. WSR is
used to synchronize the data word and to select the
left/right portion of the data sample.
Note:
WSR is high impedance if all receivers are disabled
(individual reset), during hardware reset, during
software reset, or while the DSP is in the Stop state.
While in the high impedance state, the internal
input buffer is disconnected from the signal and no
external pull-up is necessary.
