ADC Level Detect and Interrupt
The PCM9211 has the ability to monitor audio inputs, which can be used to trigger interrupt outputs on port INT1.
The ADC has a level monitor that can be set so that INT1 can be triggered whenever a specific level (referenced
to 0dBFS) is crossed. A block diagram for this function is shown in Figure 18.
Figure 18. Block Diagram for ADC Level Detection
Operation of the level detect circuitry is shown in Figure 19. The ADC level detect is flagged when either ADC
channel goes high. The flag is cleared when Register 2Dh is read.
