Multi-Channel PCM Routing Function
Overview
The PCM9211 has a multi-channel PCM routing function (maximum of eight channels) that can route
multi-channel PCM signals easily. This function is enabled by using all the MPIOs.
MPIO_A and MPIO_C are assigned as multi-channel PCM input ports and clock transition outputs (CLKST).
MPIO_B and the Main audio port are assigned as multi-channel PCM output ports. For some applications, these
multi-channel PCM output ports have five data pins. The DOUT pin and the MDOUT pin share the same data.

Initial Setting
To use the multi-channel function, set Register MCHR to '1'. In the multi-channel function, the assigned MPIO
function for Registers MPASEL[1:0], MPBSEL[2:0], and MPCSEL[2:0], are invalid; in other words, Register
MCHR has greater priority than Registers MPASEL[1:0], MPBSLE[2:0], and MPCSEL[2:0].
In multi-channel PCM mode, Register MCHR (20h) and Register MPAxHz (6Eh) must be
set to '0' in order to get the outputs from the main port.
