Bit 15 – SLPEN Sleep Enable

When set, the device stops driving the INH pin high, releasing it to high-impedance, and enters deep sleep mode. When released, if no other device is driving the INH electrical node, an external resistor will pull the node low disabling system switched power supplies.
ValueDescription
0 Normal operation
1 Sleep

Bit 14 – WKINEN WAKE_IN Wake-up Enable

When set, enables wake-up from sleep mode upon detection of a pulse on the WAKE_IN pin.
ValueDescription
0 Disable wake-up by input pulse on WAKE_IN
1 Enable wake-up by input pulse on WAKE_IN

Bit 13 – MDIWKEN MDI Wake-up Enable

When set, enables wake-up from sleep mode upon detection of activity at the MDI.
ValueDescription
0 Disable wake-up from MDI activity detection
1 Enable wake-up from MDI activity detection

Bits 12:11 – SLPINHDLY[1:0] Sleep Inhibit Delay

This field configures the delay from when sleep is first commanded to when the power supply Inhibit (INH) pin becomes high-impedance and the sleep state is entered. This delay is used to allow all nodes on a mixing segment time to go quiet before powering down.
ValueDescription
00 0 ms delay
01 50 ms delay
10 100 ms delay
11 200 ms delay

Bits 6:3 – SLPCAL[3:0] Sleep Calibration

Factory use only. Must always be written as 0000.
ValueDescription
0000 Only valid value for write
Others

Invalid on write.

Ignore on read.
