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.

description: |
|
|
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.

reg-rc:

type: int

|
description: |
|
|
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.
