Type Alias ARMED

pub type ARMED = Reg<ARMED_SPEC>;

ARMED (rw) register accessor: Indicates the armed/disarmed status of each alarm.
A write to the corresponding ALARMx register arms the alarm.
Alarms automatically disarm upon firing, but writing ones here
will disarm immediately without waiting to fire.

You can read this register and get armed::R. You can reset, write, write_with_zero this register using armed::W. You can also modify this register. See API.

For information about available fields see armed module

Implementations

impl<REG: Resettable + Writable> Reg<REG>

pub fn reset(&self)

Writes the reset value to Writable register.

Resets the register to its initial state.

pub fn write<F>(&self, f: F)

where F: FnOnce(&mut W<REG>) -> &mut W<REG>,

Writes bits to a Writable register.

You can write raw bits into a register:

periph.reg.write(|w| unsafe { w.bits(rawbits) });

or write only the fields you need:

periph.reg.write(|w| w
    .field1().bits(newfield1bits)
    .field2().set_bit()
    .field3().variant(VARIANT)
);

or an alternative way of saying the same:

periph.reg.write(|w| {
    w.field1().bits(newfield1bits);
    w.field2().set_bit();
    w.field3().variant(VARIANT)
});

In the latter case, other fields will be set to their reset value.

impl<REG: Writable> Reg<REG>

pub unsafe fn write_with_zero<F>(&self, f: F)

where F: FnOnce(&mut W<REG>) -> &mut W<REG>,

Writes 0 to a Writable register.

Similar to write, but unused bits will contain 0.

Safety

Unsafe to use with registers which don’t allow to write 0.

impl<REG: Readable + Writable> Reg<REG>

pub fn modify<F>(&self, f: F)

where for<'w> F: FnOnce(&R<REG>, &'w mut W<REG>) -> &'w mut W<REG>,

Modifies the contents of the register by reading and then writing it.

E.g. to do a read-modify-write sequence to change parts of a register:

periph.reg.modify(|r, w| unsafe { w.bits(
   r.bits() | 3
) });

or

periph.reg.modify(|_, w| w
    .field1().bits(newfield1bits)
    .field2().set_bit()
    .field3().variant(VARIANT)
);

or an alternative way of saying the same:

periph.reg.modify(|_, w| {
    w.field1().bits(newfield1bits);
    w.field2().set_bit();
    w.field3().variant(VARIANT)
});

Other fields will have the value they had before the call to modify.

impl<REG: RegisterSpec> Reg<REG>

pub fn as_ptr(&self) -> *mut REG::Ux

Returns the underlying memory address of register.

let reg_ptr = periph.reg.as_ptr();

impl<REG: Readable> Reg<REG>

pub fn read(&self) -> R<REG>

Reads the contents of a Readable register.

You can read the raw contents of a register by using bits:

let bits = periph.reg.read().bits();

or get the content of a particular field of a register:

let reader = periph.reg.read();
let bits = reader.field1().bits();
let flag = reader.field2().bit_is_set();
