47.6.8 Mono

When the Transmit Mono bit (TXMONO) in I2SMCC_MRA is set, data written to the left channel is duplicated to the right output channel. In TDM mode, with more than two channels numbered from 0, data written to the even-numbered channels is duplicated to the following odd-numbered channel. When TXMONO is set, TXRRDYx bits of I2SMCC_ISRA are always read as ‘0’ and the behavior of TXRUNFx bits is unchanged.

When the Receive Mono bit (RXMONO) in I2SMCC_MRA is set, data received from the left channel is duplicated to the right input channel. In TDM mode, with more than two channels numbered from 0, data received from the even-numbered channels is duplicated to the following odd-numbered channel. When RXMONO is set, the behavior of RXRRDYx and RXROVFx bits is unchanged.
