Struct lpc845_pac::mtb_sfr::position::R

pub struct R(_);

Register POSITION reader

Implementations

impl R

pub fn wrap(&self) -> WRAP_R

Bit 2 - This bit is set to 1 automatically when the POINTER value wraps as determined by the MASTER.MASK field in the MASTER Trace Control Register.

pub fn pointer(&self) -> POINTER_R

Bits 3:31 - Trace packet location pointer. Because a packet consists of two words, the POINTER field is the location of the first word of a packet. This field contains bits [31:3] of the address, in the SRAM, where the next trace packet will be written. The field points to an unused location and is automatically incremented. A debug agent can calculate the system address, on the AHB-Lite bus, of the SRAM location pointed to by the POSITION register using the following equation: system address = BASE + ((P + (2AWIDTH - (BASE MOD 2AWIDTH))) MOD 2AWIDTH). Where P = POSITION AND 0xFFFF_FFF8. Where BASE is the BASE register value

Methods from Deref<Target = R<POSITION_SPEC>>

pub fn bits(&self) -> REG::Ux

Reads raw bits from register.

Trait Implementations

impl Deref for R

type Target = R<POSITION_SPEC>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<R<POSITION_SPEC>> for R

fn from(reader: R<POSITION_SPEC>) -> Self
