7 Master Mode Operation

To operate TAA3020EVM-PDK in master mode, S1 and S0 on the AC-MB must first be set to "External ASI" as illustrated in Figure 4-4.

The device does not have a dedicated MCLK pin, the master clock can be applied at GPIO1, IN2P_GPI1, or MICBIAS_GPI2. Since GPI1 and GPI2 are multipurpose pins shared with analog inputs and MICBIAS, using them as the MCLK input limits the devices functionality. It is recommended to use the GPIO1 pin for MCLK.

To use GPIO1 as MCLK the MCLK signal must either be applied at the J10 terminal, or at the "External ASI" header on the AC-MB board with the other clocks. To use the "External ASI" header, it is necssary to install a 0-Ohm resistor at R11 on the EVM, which is depopulated by default.
