Struct BpCompx

pub struct BpCompx(pub u32);

Breakpoint Comparator registers, BP_COMPx (see armv6-M Architecture Reference Manual C1.8.2)

Holds a breakpoint address for comparison with instruction addresses in the Code memory region, see The system address map on page B3-224 for more information.

Tuple Fields

0: u32

Implementations

impl BpCompx

pub fn bp_match(&self) -> u32

BP_MATCH defines the behavior when the COMP address is matched:

• 00 no breakpoint matching.
• 01 breakpoint on lower halfword, upper is unaffected.
• 10 breakpoint on upper halfword, lower is unaffected.
• 11 breakpoint on both lower and upper halfwords.
• The field is UNKNOWN on reset.

pub fn comp(&self) -> u32

Stores bits [28:2] of the comparison address. The comparison address is compared with the address from the Code memory region. Bits [31:29] and [1:0] of the comparison address are zero.

The field is UNKNOWN on power-on reset.

pub fn enable(&self) -> bool

Enables the comparator:

0: comparator is disabled.
1: comparator is enabled.

This bit is set to 0 on a power-on reset.

pub fn set_bp_match(&mut self, value: u32)

BP_MATCH defines the behavior when the COMP address is matched:

• 00 no breakpoint matching.
• 01 breakpoint on lower halfword, upper is unaffected.
• 10 breakpoint on upper halfword, lower is unaffected.
• 11 breakpoint on both lower and upper halfwords.
• The field is UNKNOWN on reset.

pub fn set_comp(&mut self, value: u32)

Stores bits [28:2] of the comparison address. The comparison address is compared with the address from the Code memory region. Bits [31:29] and [1:0] of the comparison address are zero.

The field is UNKNOWN on power-on reset.

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

Enables the comparator:

0: comparator is disabled.
1: comparator is enabled.

This bit is set to 0 on a power-on reset.

Trait Implementations

impl From<BpCompx> for u32

fn from(value: BpCompx) -> Self

Converts to this type from the input type.

impl From<u32> for BpCompx

fn from(value: u32) -> Self

Converts to this type from the input type.

impl MemoryMappedRegister<u32> for BpCompx

const ADDRESS_OFFSET: u64 = 3_758_104_584u64

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 = "BP_CTRL0"

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.
