Module atsamd_hal::clock
source · [−]Expand description
Configuring the system clock sources.
You will typically need to create an instance of GenericClockController
before you can set up most of the peripherals on the atsamd21 device.
The other types in this module are used to enforce at compile time
that the peripherals have been correctly configured.
Structs
A typed token that indicates that the clock for the peripheral(s)
with the matching name has been configured.
The effective clock frequency is available via the
freq method,
or by converting the object into a Hertz instance.
The peripheral initialization code will typically require passing
in this object to prove at compile time that the clock has been
correctly initialized.A typed token that indicates that the clock for the peripheral(s)
with the matching name has been configured.

Can be converted into the effective clock frequency.
Its primary purpose is to be passed in to methods
such as
GenericClockController::tcc2_tc3 to configure
the clock for a peripheral.GenericClockController encapsulates the GCLK hardware.
It provides a type safe way to configure the system clocks.
Initializing the GenericClockController instance configures
the system to run at 48Mhz by setting gclk1 as a 32khz source
and feeding it into the DFLL48 hardware which in turn drives
gclk0 at 48Mhz.A typed token that indicates that the clock for the peripheral(s)
