CONN_PHONEJACK_STEREO_CMS
The AT73C213 DAC is used for the I²S audio output. It's controlled by the AT91CAP9 SPI0 bus, with
SPI0_NPCS2 chip select. I²S DAC dedicated serial interface is managed by AT91CAP9 SCC0 bus.
The implementation is shown below:
Analog input adaptation is realized by an AD8040 low-power high-speed rail-to-rail IO amplifier.
ADC[1..4] output signals of the amplifier drive the AD[0..7] ADC embedded in the AT91CAP9.
Table 2-18.
