Struct FpCtrl

pub struct FpCtrl(pub u32);

Flash Patch Control Register, FP_CTRL (see armv7-M Architecture Reference Manual C1.11.3)

Tuple Fields

0: u32

Implementations

impl FpCtrl

pub fn rev(&self) -> u32

Flash Patch breakpoint architecture revision:

0b0000 Flash Patch breakpoint version 1.
0b0001 Flash Patch breakpoint version 2. Supports breakpoints on any location in the 4GB address range.

pub fn num_lit(&self) -> u32

The number of literal address comparators supported, starting from NUM_CODE upwards. UNK/SBZP if Flash Patch is not implemented. Flash Patch is not implemented if FP_REMAP[29] is 0.

If this field is zero, the implementation does not support literal comparators.

pub fn enable(&self) -> bool

Enable bit for the FPB:

0: Flash Patch breakpoint disabled.
1: Flash Patch breakpoint enabled.

A power-on reset clears this bit to 0.

pub fn set_key(&mut self, value: bool)

On any write to FP_CTRL, this bit must be 1. A write to the register with this bit set to zero is ignored. The Flash Patch Breakpoint unit ignores the write unless this bit is 1.

pub fn set_enable(&mut self, value: bool)

Enable bit for the FPB:

0: Flash Patch breakpoint disabled.
1: Flash Patch breakpoint enabled.

A power-on reset clears this bit to 0.

impl FpCtrl

pub fn num_code(&self) -> u32

The number of instruction address comparators. If NUM_CODE is zero, the implementation does not support any instruction address comparators.

Trait Implementations

impl<T> BitRange<T> for FpCtrl

where u32: BitRange<T>,

fn bit_range(&self, msb: usize, lsb: usize) -> T

Get a range of bits.

impl<T> BitRangeMut<T> for FpCtrl

where u32: BitRangeMut<T>,

fn set_bit_range(&mut self, msb: usize, lsb: usize, value: T)

Set a range of bits.

impl Clone for FpCtrl

fn clone(&self) -> FpCtrl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FpCtrl

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

Formats the value using the given formatter.

impl From<FpCtrl> for u32

fn from(value: FpCtrl) -> Self

Converts to this type from the input type.

impl From<u32> for FpCtrl

fn from(value: u32) -> Self

Converts to this type from the input type.

impl MemoryMappedRegister<u32> for FpCtrl

const ADDRESS_OFFSET: u64 = 3_758_104_576u64

The register’s address in the target memory. For some architectures (e.g. ARM Cortex-A) this address is offset from a base address. For others (e.g. ARM Cortex-M, RISC-V) this address is absolute.

const NAME: &'static str = "FP_CTRL"

The register’s name.

fn get_mmio_address_from_base( base_address: u64, ) -> Result<u64, RegisterAddressOutOfBounds>

Get the register’s address in the memory map. For architectures like ARM Cortex-A, this address is offset from a base address, which must be supplied when calling this method. For others (e.g. ARM Cortex-M, RISC-V) where this address is a constant, please use MemoryMappedRegister::get_mmio_address.

fn get_mmio_address() -> u64

Get the register’s address in the memory map. For architectures ARM Cortex-M and RISC-V, this address is constant value stored as part of MemoryMappedRegister::ADDRESS_OFFSET. For other architectures (e.g. ARM Cortex-A) where this address is offset from a base address, please use MemoryMappedRegister::get_mmio_address_from_base.
