Audio Output Formats
The ES9826 supports multiple serial output data formats.
In Hardware mode, see Input/Output mode table to configure the output format. Hardware mode is limited to a single output
format. Since S/PDIF and PCM data are both on GPIO3, the user must choose between the two options.
In Software mode, the TDM encoder (used for TDM and PCM) is enabled, and the S/PDIF encoder is disabled by default.
In Software mode, both PCM and S/PDIF outputs can be used in parallel since S/PDIF can be mapped to any GPIO.
PCM (I2S, LJ)
Data is packaged as 2 channel slots per data line. Either ADC can be mapped to either the first or second slot of the frame
through Registers 7[4:0] & 8[4:0] TDM_SLOT_SEL_CHx. Data is latched on the positive edge of BCLK.
