LMODE: Power-save Mode Select of Stereo Line Output A (Table 73, Table 74)
0: Using a same connector for both Line input and output
1: Line output and input are independent (default)
PMDM3-0: Input Signal Select with Digital Microphone (Table 8, Table 9)
0: Power down (default)
1: Power up
These bits are enabled when DMIC bit = “1”. ADC digital block is powered-down by PMDM3-0 bits = “0” when
selecting a digital microphone input (DMIC bit = “1”).
Each block can be powered-down respectively by writing “0” in each bit of the address 19H~1CH. When the PDN pin
is “L”, all blocks are powered-down regardless of setting of these addresses. In this case, register is initialized to the
default value.
When all power management bits are “0”, all blocks are powered-down. The register values remain unchanged. Power
supply current is 50μA(typ) in this case. For fully shut down (typ. 0μA), the PDN pin should be “L”.
