RPAB = 0: Port A enabled (DRA input selected)
RPAB = 1: Port B enabled (DRB input selected)
TE = 0: Transmit PCM data change on rising edge of MCLK
TE = 1: Transmit PCM data change on falling edge of MCLK
PC1-PC0 = Selection of the channel for the PCM access data via MCU.
WR = 1: Setting this bit, receive PCM data writing via MCU (after A/μ decoding) is
enabled on selected channel and IPCM interrupt is generated every time FS signal
becomes active, together to the set of the WRD bit in the PCMCTRL register.
A data byte must be written every 125 μs, if data is not replaced the old value is
inserted again but the PMW bit is set to 1 in the PCMCTRL register.
RR = 1: Setting this bit, transmit PCM data reading (after A/μ encoding) via MCU is
enabled on selected channel and IPCM interrupt is generated every time that data are
available, together to the set of the RRD bit in the PCMCTRL register.
A data byte must be read every 125 μS, if data is not read the new value is written in
the PCM access register but the POW bit is set to 1 in the PCMCTRL register.
