Enum InitStep 

pub enum InitStep {
    CkeLowWait {
        cycles: u64,
    },
    Wait {
        cycles: u64,
    },
    PrechargeAll,
    Refresh,
    LoadMode {
        reg: ModeReg,
        a: u16,
    },
}

One step of the DDR2 power-up init sequence.

Variants

CkeLowWait

Hold CKE low (DESELECT) for cycles — the ≥200 µs power-up wait — then raise CKE.

Fields

cycles: u64

Wait

A NOP idle wait of cycles (satisfies tRP / tMRD / tRFC / tDLLK between commands).

Fields

cycles: u64

PrechargeAll

PRECHARGE ALL banks (A10 = 1).

Refresh

AUTO-REFRESH.

LoadMode

Load a mode register with the 13-bit address payload (opcode).

Fields

reg: ModeReg

a: u16

Trait Implementations

impl Clone for InitStep

fn clone(&self) -> InitStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitStep

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for InitStep

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

impl Copy for InitStep
