PRODUCTION DATA.
The PCM186x four-channel software-controlled devices offer an additional DOUT through the use of a GPIO that has its rate synchronized with the primary DOUT. DOUT2 is configured using the digital mixer, shown in Digital Mixing Function. In TDM Modes, DOUT2 is not available.
The GPIO used for DOUT2 can be set using registers. GPIO0 is used for SPI-MOSI in SPI mode, however, it can be retasked for DOUT2 duties if MOSI is not required.GPIO0_FUNC (Page.0 0x10), GPIO1_FUNC (Page.0 0x10), GPIO2_FUNC (Page.0 0x11), or GPIO3_FUNC (Page.0 0x11) can be used to set GPIOx to DOUT2
