<level> voltage threshold in volts
([d]d.ddV) or raw ADC steps
(0xhhh)
<time> number of consecutive seconds
the voltage must remain above
or below the threshold value for
the trigger to activate
VL WAKE: <ON/OFF>, <</>>[!]<level> FOR <time> s 1.3.3 Voltage level wakeup trigger. Same format as the
voltage level sleep trigger.
VCHG WAKE: <ON/OFF>, [+/-][!]<change> IN <time> ms 1.3.4 Voltage change wakeup trigger:
<ON/OFF> trigger on/off
[+/-] specifies whether the trigger
detects only rising voltage (+),
only falling voltage (-), or a
voltage change in any direction
(no sign)
[!] this designator indicates that the
voltage change setting is invalid,
i.e. cannot be achieved with the
current voltage calibration
<change> voltage change in volts
([d]d.ddV) or raw ADC steps
(0xhhh)
<time> number of milliseconds between
voltage samples
SLEEP [delay]
Enter sleep mode. Takes optional delay parameter
in seconds. When the delay is specified, the command
prints “OK”, and returns to the command prompt. The
sleep mode will be entered after the specified delay
time. When the parameter is empty or 0 seconds delay
is specified, the command will print “OK” and
immediately put the device to sleep.
SLLT
Report last sleep/wakeup triggers, in this format:
SLEEP:
WAKE:
Sleep trigger can be one of the following:
Trigger Description
NONE
Device did not enter sleep mode
since last reset
CMD STSLEEP or ATLP command
UART UART inactivity timeout
EXT External sleep control input
VL Voltage level
Wakeup trigger can be one of the following:
Trigger Description
NONE
Device did not wake up from sleep
since last reset
UART UART Rx pulse
EXT External sleep control input
VL Voltage level
VCHG Voltage change
Example:
SLEEP: CMD
WAKE: UART
SLPCP 0|1
Set polarity of the PWR_CTRL output.
0: Normal power = HIGH, Low power mode = LOW
1: Normal power = LOW, Low power mode = HIGH
The default setting is 0.
Note: This command is available only for STN1110
stand-alone IC.
