Sleep commands
The following commands are sleep commands.
SM (Sleep Mode)
Sets or displays the sleep mode of the device.
Normal mode is always awake. Pin sleep modes allow you to wake the device with the SLEEP_
REQUEST line. Asynchronous cyclic mode sleeps for
SP
time and briefly wakes, checking for activity.
Sleep Support mode is always awake but can effectively communicate with
SM
8 nodes. Synchronized
Cyclic Sleep nodes sleep for
SP
and wake for
ST
time.
Synchronous modes are not compatible with asynchronous modes.
Parameter range
0, 1, 4, 5, 7, 8
Parameter Description
0
Normal.
1
Asynchronous Pin Sleep. In this mode, the SLEEP_RQ line controls the sleep/wake
state of the device.
2
N/A
3
N/A
4
Asynchronous Cyclic Sleep. In this mode, the device periodically sleeps and wakes
based on the
SP
and
ST
commands.
5
Asynchronous Cyclic Sleep Pin Wake. When you assert the SLEEP_RQ pin, the device
enters a cyclic sleep mode similar to Asynchronous Cyclic Sleep. When you de-assert
the SLEEP_RQ pin, the device immediately wakes up. The device does not sleep when
you de-assert the SLEEP_RQ pin.

7
Sleep Support
8
Synchronized Cyclic Sleep
