4.0 Registers
4.16 PRA Transmit Write
with Bit 0.
The value of this register is only relevant if the corresponding MODE bit of TX_PRA_CTRL0 is set. A new
written value takes effect starting with the next PCM multiframe following the register write access cycle
completion. Each bit of this register is used in the odd frames of the PCM multiframe.
