5.4.59 Sleep Control 1 Register - Rev D

This register is only valid for devices of Revision D0 and later.

Important: When writing to this register, use a read-modify-write operation to avoid accidental modifications to RESERVED fields. Failure to use a read-modify-write operation may result in adverse operation and unexpected results.

Bit 15 – WIOEN WAKE_IO Enable

When set, this bit configures the WAKE_IN pin to be combined with the WAKE_OUT as WAKE_IO. The WAKE_OUT pin is not used in this mode.

Value	Description
`0`	WAKE_IN and WAKE_OUT are separate pins.
`1`	WAKE_IO is enabled as a combined WAKE_IN and WAKE_OUT. The WAKE_OUT pin is not used.

Bit 5 – WIPOL WAKE_IN Polarity

This bit configures the polarity of the pulse on the WAKE_IN pin that will wake the device from sleep. While WAKE_IO is active, this bit configures the wake input and wake output mode.

Value	Description
`0`	Device will wake from an active LOW pulse on WAKE_IN pin. WAKE_IO will trigger upon active LOW pulse, will output an active LOW wake output.
`1`	Device will wake from an active HIGH pulse on WAKE_IN pin. WAKE_IO will trigger upon active HIGH pulse, will output an active HIGH wake output.

Bit 2 – WKOREQ WAKE_OUT Request

Writing a ‘1’ to this bit will cause the device will generate a wake-up pulse on WAKE_OUT, or, when enabled, WAKE_IO pin.

Note: This bit is self clearing.

Value	Description
`0`	No wake-up pulse signaling (normal operation)
`1`	Generate a wake-up pulse on WAKE_OUT/WAKE_IO

Bit 1 – WKOFWDEN Wake Forward Enable

Enable the generation of a WAKE_OUT pulse when a wake indication is detected by MDI activity or assertion of the WAKE_IN pin.

Value	Description
`0`	Disable generation of a pulse on WAKE_OUT on wake-up
`1`	Enable generation of a pulse on WAKE_OUT on wake-up

Bit 0 – MDIFWDEN MDI Forward Enable

This bit will enable the generation of activity signaling on the MDI when a wake indication is detected by the assertion of the WAKE_IN pin.

Value	Description
`0`	Disable generation MDI wake signaling upon wake-up from WAKE_IN
`1`	Enable generation MDI wake signaling upon wake-up from WAKE_IN
