Description
Atmel SAM Timer Counter (TC) node
Properties
Properties not inherited from the base binding file.

|
|
Timer / Counter channel to use, channel 0 is the default.
Valid range: 0 - 2
|
|
|
Clock source selection as defined by TCCLKS bit-field of TC_CMR
register. Consult the datasheet for the details.
|
|
|
If set to true the `clk` property is ignored. Instead the TC module is
driven directly via MCLK. Only supported on sam4e, same70, same70b,
samv71, samv71b SoC series.
|
|
|
Alternate value of the CMR (Channel Mode Register) register.
If specified this value will be written to the register during driver
instance initialization instead of the default. It can be used to
configure the timer / counter in the custom mode. Together with other
properties like channel-num, pinctrl-0 this allows e.g. to configure
the driver to count events generated on the TIOA, TIOB signal connected
to the external pin.
|
|
|
Register C compare/match value. RC can be used as compare/match unit
for an specific timer unit. Their use depends on how timer channel
is configured,see reg-cmr. It can be used as trigger for both input
capture or counter mode, or even as event source. The RC register
behavior is SoC dependent. For more information and use cases,
check SoC datasheet and application notes.
|
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
|
|
|
Pin configuration/s for the second state. See pinctrl-0.
|
|
|
Pin configuration/s for the third state. See pinctrl-0.
|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|
Pin configuration/s for the fifth state. See pinctrl-0.
|
|
|
Names for the provided states. The number of names needs to match the
number of states.
|
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 “atmel,sam-tc” compatible.

|
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.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
