Struct Refclock 

pub struct Refclock { /* private fields */ }

Reference clock generator singleton

Implementations

impl Refclock

pub fn enable(&self)

Enable reference clock generator

pub fn disable(&self)

Disable reference clock generator

pub fn output_enable(&self)

Enable clock output

pub fn output_disable(&self)

Disable clock output

pub fn select_source(&self, s: Source) -> Result<(), Error>

Select a clock source

Returns an InvalidState error if called when active. Call this before enable() or after disable()

pub fn set_divisor(&self, div_q8: u32) -> Result<(), Error>

Set reference clock divisor

div_q8 is the fractional clock divisor in Q16.8 representation. The minimum value is 2 (represented as 0x000200). The maximum value is 2^16 - 1/(2^8) (represented as 0xffffff). div_q8 refers to the total clock ratio including an additional /2 division described in the data sheet. Returns an InvalidArgument error if the divisor is out of range and an InvalidState error if called during an ongoing divisor change operation.

Remark: not clear (to me) from the documentation if changing the integer part of the divisor works when the reference clock module is active; needs to be tested.

pub fn set_divisor_ongoing(&self) -> bool

Check if a clock divisor setting operation is ongoing.

Returns false if the ACTIVE bit is not set regardless of whether a divisor setting has previously been initiated.
