Implementations

impl CrAlternate

pub const fn dcnt(&self) -> u16

count of data to transfer during a read or write message, in bytes (when I3C is acting as controller) Linear encoding up to 64 Kbytes -1. …

pub fn set_dcnt(&mut self, val: u16)

count of data to transfer during a read or write message, in bytes (when I3C is acting as controller) Linear encoding up to 64 Kbytes -1. …

pub const fn ccc(&self) -> u8

8-bit CCC code (when I3C is acting as controller) If Bit[23]=CCC[7]=1, this is the 1st part of an I3C SDR direct CCC command. If Bit[23]=CCC[7]=0, this is an I3C SDR broadcast CCC command (including ENTDAA and ENTHDR0).

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

8-bit CCC code (when I3C is acting as controller) If Bit[23]=CCC[7]=1, this is the 1st part of an I3C SDR direct CCC command. If Bit[23]=CCC[7]=0, this is an I3C SDR broadcast CCC command (including ENTDAA and ENTHDR0).

pub const fn mtype(&self) -> u8

message type (when I3C is acting as controller) Bits[23:16] (CCC[7:0]) is the emitted 8-bit CCC code If Bit[23]=CCC[7]=1: this is the 1st part of an I3C SDR direct CCC command The transferred direct CCC command message is: {S / S+7’h7E +RnW=0 / Sr+} + (direct CCC + T) + (8-bit Data + T) + Sr After a S (START), depending on I3C_CFGR.NOARBH, the arbitrable header (7’h7E+RnW=0) is inserted or not. Sr+: after a Sr (Repeated Start), the hardware automatically inserts (7’h7E+R/W). If Bit[23]=CCC[7]=0: this is an I3C SDR broadcast CCC command (including ENTDAA and ENTHDR0) The transferred broadcast CCC command message is: {S / S+7’h7E +RnW=0 / Sr+} + (broadcast CCC + T) + (8-bit Data + T)* + Sr/P After a S (START), depending on I3C_CFGR.NOARBH, the arbitrable header (7’h7E+RnW=0) is inserted or not. Sr+*: after a Sr (Repeated Start), the hardware automatically inserts (7’h7E+R/W). others: reserved.

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

message type (when I3C is acting as controller) Bits[23:16] (CCC[7:0]) is the emitted 8-bit CCC code If Bit[23]=CCC[7]=1: this is the 1st part of an I3C SDR direct CCC command The transferred direct CCC command message is: {S / S+7’h7E +RnW=0 / Sr+} + (direct CCC + T) + (8-bit Data + T) + Sr After a S (START), depending on I3C_CFGR.NOARBH, the arbitrable header (7’h7E+RnW=0) is inserted or not. Sr+: after a Sr (Repeated Start), the hardware automatically inserts (7’h7E+R/W). If Bit[23]=CCC[7]=0: this is an I3C SDR broadcast CCC command (including ENTDAA and ENTHDR0) The transferred broadcast CCC command message is: {S / S+7’h7E +RnW=0 / Sr+} + (broadcast CCC + T) + (8-bit Data + T)* + Sr/P After a S (START), depending on I3C_CFGR.NOARBH, the arbitrable header (7’h7E+RnW=0) is inserted or not. Sr+*: after a Sr (Repeated Start), the hardware automatically inserts (7’h7E+R/W). others: reserved.

pub const fn mend(&self) -> Mend

message end type (when I3C is acting as controller).

pub fn set_mend(&mut self, val: Mend)

message end type (when I3C is acting as controller).

Trait Implementations

impl Clone for CrAlternate

fn clone(&self) -> CrAlternate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for CrAlternate

fn default() -> CrAlternate

Returns the “default value” for a type.

impl PartialEq for CrAlternate

fn eq(&self, other: &CrAlternate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
