Implementations

impl Timer

pub const fn nonsec_write(&self) -> bool

Control whether Non-secure software can write to the timer registers. All other registers are hardwired to be inaccessible to Non-secure.

pub fn set_nonsec_write(&mut self, val: bool)

Control whether Non-secure software can write to the timer registers. All other registers are hardwired to be inaccessible to Non-secure.

pub const fn run(&self) -> bool

Timer enable. Setting this bit causes the timer to begin counting up from its current value. Clearing this bit stops the timer from counting. Before enabling the timer, set the POWMAN_LPOSC_FREQ* and POWMAN_XOSC_FREQ* registers to configure the count rate, and initialise the current time by writing to SET_TIME_63TO48 through SET_TIME_15TO0. You must not write to the SET_TIME_x registers when the timer is running. Once configured, start the timer by setting POWMAN_TIMER_RUN=1. This will start the timer running from the LPOSC. When the XOSC is available switch the reference clock to XOSC then select it as the timer clock by setting POWMAN_TIMER_USE_XOSC=1

pub fn set_run(&mut self, val: bool)

pub const fn clear(&self) -> bool

Clears the timer, does not disable the timer and does not affect the alarm. This control can be written at any time.

pub fn set_clear(&mut self, val: bool)

Clears the timer, does not disable the timer and does not affect the alarm. This control can be written at any time.

pub const fn alarm_enab(&self) -> bool

Enables the alarm. The alarm must be disabled while writing the alarm time.

pub fn set_alarm_enab(&mut self, val: bool)

Enables the alarm. The alarm must be disabled while writing the alarm time.

pub const fn pwrup_on_alarm(&self) -> bool

Alarm wakes the chip from low power mode

pub fn set_pwrup_on_alarm(&mut self, val: bool)

Alarm wakes the chip from low power mode

pub const fn alarm(&self) -> bool

Alarm has fired. Write to 1 to clear the alarm.

pub fn set_alarm(&mut self, val: bool)

Alarm has fired. Write to 1 to clear the alarm.

pub const fn use_lposc(&self) -> bool

Switch to lposc as the source of the 1kHz timer tick

pub fn set_use_lposc(&mut self, val: bool)

Switch to lposc as the source of the 1kHz timer tick

pub const fn use_xosc(&self) -> bool

switch to xosc as the source of the 1kHz timer tick

pub fn set_use_xosc(&mut self, val: bool)

switch to xosc as the source of the 1kHz timer tick

pub const fn use_gpio_1khz(&self) -> bool

switch to gpio as the source of the 1kHz timer tick

pub fn set_use_gpio_1khz(&mut self, val: bool)

switch to gpio as the source of the 1kHz timer tick

pub const fn use_gpio_1hz(&self) -> bool

Selects the gpio source as the reference for the sec counter. The msec counter will continue to use the lposc or xosc reference.

pub fn set_use_gpio_1hz(&mut self, val: bool)

Selects the gpio source as the reference for the sec counter. The msec counter will continue to use the lposc or xosc reference.

pub const fn using_xosc(&self) -> bool

Timer is running from xosc

pub fn set_using_xosc(&mut self, val: bool)

Timer is running from xosc

pub const fn using_lposc(&self) -> bool

Timer is running from lposc

pub fn set_using_lposc(&mut self, val: bool)

Timer is running from lposc

pub const fn using_gpio_1khz(&self) -> bool

Timer is running from a 1khz gpio source

pub fn set_using_gpio_1khz(&mut self, val: bool)

Timer is running from a 1khz gpio source

pub const fn using_gpio_1hz(&self) -> bool

Timer is synchronised to a 1hz gpio source

pub fn set_using_gpio_1hz(&mut self, val: bool)

Timer is synchronised to a 1hz gpio source

Trait Implementations

impl Clone for Timer

fn clone(&self) -> Timer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Timer

fn default() -> Timer

Returns the “default value” for a type.

impl PartialEq for Timer

fn eq(&self, other: &Timer) -> 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.
