POWER-DOWN OPERATION
The PCM4201 can be forced to a power-down state by
applying a low level to the RST input (pin 7) for a minimum
of 65,536 system clock cycles. In power-down mode, all
internal clocks are stopped, and the output data pin is
forced low. The system clock may then be removed to
conserve additional power. Before exiting power-down
mode, the system and audio clocks should be restarted.
Once the clocks are active, the RST input may be driven
high, which initiates a reset initialization sequence.
Figure 10 illustrates the state of the output data pins
before, during, and upon exiting the power down state.
