Struct SystemTimer

Source 
pub struct SystemTimer {
    pub alarm0: Alarm,
    pub alarm1: Alarm,
    pub alarm2: Alarm,
}
Available on crate feature unstable only.
Expand description

System Timer driver.

Fields§

§alarm0: Alarm

Alarm 0.

§alarm1: Alarm

Alarm 1.

§alarm2: Alarm

Alarm 2.

Implementations§

Source§

impl SystemTimer

Source

pub const BIT_MASK: u64 = 18_446_744_073_709_551_615u64

Bitmask to be applied to the raw register value.

Source

pub fn ticks_per_second() -> u64

Returns the tick frequency of the underlying timer unit.

Source

pub fn new(_systimer: SYSTIMER) -> Self

Create a new instance.

Source

pub fn unit_value(unit: Unit) -> u64

Get the current count of the given unit in the System Timer.

Source

pub unsafe fn set_unit_value(unit: Unit, value: u64)

Set the value of the counter immediately. If the unit is at work, the counter will continue to count up from the new reloaded value.

This can be used to load back the sleep time recorded by RTC timer via software after Light-sleep

§Safety
  • Modifying a unit’s count whilst Alarms are using it may cause unexpected behaviour
  • Any modification of the unit0 count will affect Instant::now
