Counter clock frequency
This property is required. |
|
|
The frequency of the counter is divided by this value.
This property is required. |
|
|
Selects the clock to be used by the LPMTR prescaler/glitch filter.
In time counter mode, this field selects the input clock to the prescaler.
In pulse counter mode, this field selects the input clock to the glitch filter.
The clock connections vary by device, see the device reference manual for
more details.
This property is required. Legal values: |
|
|
When LPTMR is in Pulse mode, this value
will be used to determine the "rising-edge
source pin" to increment the lptmr counter.
|
|
|
When LPTMR is in Pulse mode, this value
will set the counter to active low.
|
|
|
Represents the width of the counter in bits.
This property is required. |
|
|
When in prescaler mode, the counter is incremented every
2 ^ [prescaler-glitch-filter] clock cycles.
When in pulse mode, the counter is incremented every
2 ^ [prescaler-glitch-filter] rising edges detected
by the pin configured from the input-pin value.
Note, that the pulse mode cannot be 2 ^ 16.
Default value: Legal values: |
|
|
This value determines rather the LPTMR is configured
for Time-Counter mode or for Pulse mode.
0 <- LPTMR is configured for Time Counter Mode.
1 <- LPTMR is configured for Pulse Mode.
Legal values: |
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nxp,lptmr” compatible.

|
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
