Struct BusTiming 

pub struct BusTiming {
    pub scl_pp_low: u8,
    pub scl_i3c_high: u8,
    pub scl_od_low: u8,
    pub scl_i2c_high: u8,
    pub bus_free: u8,
    pub bus_idle: u8,
    pub sda_hold_1_5: bool,
    pub wait_time: u8,
}

SCL waveform timing in kernel clock cycles.

These values correspond to the fields in TIMINGR0 and TIMINGR1. The ST CubeMX / I3C_CtrlTimingComputation utility can compute them from desired bus frequencies; the defaults match the Nucleo-N657X0 I3C examples.

Fields

scl_pp_low: u8

SCL low duration in I3C push-pull phases (TIMINGR0.SCLL_PP).

scl_i3c_high: u8

SCL high duration for I3C messages (TIMINGR0.SCLH_I3C).

scl_od_low: u8

SCL low duration in open-drain phases (TIMINGR0.SCLL_OD).

scl_i2c_high: u8

SCL high duration for legacy I2C messages (TIMINGR0.SCLH_I2C).

bus_free: u8

Bus free duration (TIMINGR1.FREE).

bus_idle: u8

Bus idle / hot-join duration (TIMINGR1.AVAL).

sda_hold_1_5: bool

SDA hold time: true = 1.5 cycles, false = 0.5 cycles (TIMINGR1.SDA_HD).

wait_time: u8

Activity state of new controller (TIMINGR1.ASNCR), typically 0.
