Implementations

impl Getmxdsr

pub const fn hoffas(&self) -> u8

controller hand-off activity state This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and indicates in which initial activity state the (other) current controller should expect the I3C bus after a controller-role hand-off to this controller-capable I3C, when returning the defining byte CRHDLY (0x91) to a GETMXDS CCC. This 2-bit field is used to return the CRHDLY1 byte in response to the GETCAPS CCC format 3, in order to state which is the activity state of this I3C when becoming controller after a controller-role hand-off, and consequently the time the former controller should wait before testing this I3C to be confirmed its ownership.

pub fn set_hoffas(&mut self, val: u8)

controller hand-off activity state This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and indicates in which initial activity state the (other) current controller should expect the I3C bus after a controller-role hand-off to this controller-capable I3C, when returning the defining byte CRHDLY (0x91) to a GETMXDS CCC. This 2-bit field is used to return the CRHDLY1 byte in response to the GETCAPS CCC format 3, in order to state which is the activity state of this I3C when becoming controller after a controller-role hand-off, and consequently the time the former controller should wait before testing this I3C to be confirmed its ownership.

pub const fn fmt(&self) -> u8

GETMXDS CCC format.

pub fn set_fmt(&mut self, val: u8)

GETMXDS CCC format.

pub const fn rdturn(&self) -> u8

programmed byte of the 3-byte MaxRdTurn (maximum read turnaround byte) This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and writes the value of the selected byte (via the FMT[1:0] field) of the 3-byte MaxRdTurn which is returned in response to the GETMXDS CCC format 2 to encode the maximum read turnaround time.

pub fn set_rdturn(&mut self, val: u8)

programmed byte of the 3-byte MaxRdTurn (maximum read turnaround byte) This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and writes the value of the selected byte (via the FMT[1:0] field) of the 3-byte MaxRdTurn which is returned in response to the GETMXDS CCC format 2 to encode the maximum read turnaround time.

pub const fn tsco(&self) -> bool

clock-to-data turnaround time (tSCO) This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and is used to specify the clock-to-data turnaround time tSCO (vs the value of 12 ns). This bit is used by the hardware in response to the GETMXDS CCC to return the encoded clock-to-data turnaround time via the returned MaxRd[5:3] bits.

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

clock-to-data turnaround time (tSCO) This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and is used to specify the clock-to-data turnaround time tSCO (vs the value of 12 ns). This bit is used by the hardware in response to the GETMXDS CCC to return the encoded clock-to-data turnaround time via the returned MaxRd[5:3] bits.

Trait Implementations

impl Clone for Getmxdsr

fn clone(&self) -> Getmxdsr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Getmxdsr

fn default() -> Getmxdsr

Returns the “default value” for a type.

impl PartialEq for Getmxdsr

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