Implementations

impl MacSubSecondIncrement

pub const fn ssinc(&self) -> u8

Sub-second Increment Value. The value programmed in this field is accumulated every clock cycle (of clk_ptp_i) with the contents of the sub-second register. For example, when the PTP clock is 50 MHz (period is 20 ns), you must program 20 (0x14) when the System Time Nanoseconds register has an accuracy of 1 ns [Bit 9 (TSCTRLSSR) is set in MAC_Timestamp_Control]. When TSCTRLSSR is clear, the Nanoseconds register has a resolution of 0.465 ns. In this case, you must program a value of 43 (0x2B) which is derived by 20 ns/0.465.

pub const fn set_ssinc(&mut self, val: u8)

Sub-second Increment Value. The value programmed in this field is accumulated every clock cycle (of clk_ptp_i) with the contents of the sub-second register. For example, when the PTP clock is 50 MHz (period is 20 ns), you must program 20 (0x14) when the System Time Nanoseconds register has an accuracy of 1 ns [Bit 9 (TSCTRLSSR) is set in MAC_Timestamp_Control]. When TSCTRLSSR is clear, the Nanoseconds register has a resolution of 0.465 ns. In this case, you must program a value of 43 (0x2B) which is derived by 20 ns/0.465.

Trait Implementations

impl Clone for MacSubSecondIncrement

fn clone(&self) -> MacSubSecondIncrement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MacSubSecondIncrement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MacSubSecondIncrement

fn default() -> MacSubSecondIncrement

Returns the “default value” for a type.

impl PartialEq for MacSubSecondIncrement

fn eq(&self, other: &MacSubSecondIncrement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
