3.4.1 Interface Section
This section (refer to Figure 10 ) controls the behavior of the I
2
S port (BCLK, LRCLK, DIN, and DOUT
pins). In this EVM, the audio port transfers 16-bit data in I
2
S format, and the codec reference sample rate
is 44.1 kHz.
The TSC2111 is programmed as an I
2
S slave by default. The onboard processor TAS1020B is the master,
which generates the BCLK and LRCLK signal. If the TSC2111 is used as a master, the onboard processor
should be disabled and the I
2
S port should be detached from the processor by turning off the onboard I
2
S
interface. Refer to Table 2 in the Default Configurations 2.2 section.
