Struct itsybitsy_m4::GenericClockController

pub struct GenericClockController { /* private fields */ }

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 120MHz by taking the DFLL48 and feeding it into the DPLL0 hardware which multiplies the signal by 2.5x.

Implementations

pub fn with_external_32kosc( gclk: GCLK, mclk: &mut MCLK, osc32kctrl: &mut OSC32KCTRL, oscctrl: &mut OSCCTRL, nvmctrl: &mut NVMCTRL ) -> GenericClockController

Reset the clock controller, configure the system to run at 120Mhz and reset various clock dividers.

pub fn gclk0(&mut self) -> GClock

Returns a GClock for gclk0, the 120MHz oscillator.

pub fn gclk1(&mut self) -> GClock

Returns a GClock for gclk1, the 32KHz oscillator.

pub fn get_gclk(&mut self, gclk: GEN_A) -> Option<GClock>

Returns the GClock for the specified clock generator. If that clock generator has not yet been configured, returns None.

pub fn configure_gclk_divider_and_source( &mut self, gclk: GEN_A, divider: u16, src: SRC_A, improve_duty_cycle: bool ) -> Option<GClock>

Configures a clock generator with the specified divider and source. divider is a linear divider to be applied to the clock source. While the hardware also supports an exponential divider, this function doesn’t expose that functionality at this time. improve_duty_cycle is a boolean that, when set to true, enables a 50/50 duty cycle for odd divider values.
