Struct Config 

#[non_exhaustive]
pub struct Config {
    pub frequency: Frequency,
    pub spi_mode: Mode,
    pub lines: Lines,
    pub address_mode: AddressMode,
    pub read_opcode: u8,
    pub write_opcode: u8,

sQSPI driver configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

frequency: Frequency

Bus frequency.

spi_mode: Mode

SPI clock polarity and phase.

lines: Lines

Multi-line mode used for the read/write data phases.

address_mode: AddressMode

Flash addressing mode (24-bit or 32-bit).

read_opcode: u8

Read command opcode (e.g. 0xEB Quad I/O Read, 0x03 Read).

write_opcode: u8

Page-program command opcode (e.g. 0x38 Quad I/O PP, 0x02 Page Program).

read_dummy_cycles: u8

Dummy/wait cycles after the address phase of a read. Opcode- and flash-specific: MX25R 0xEB → 6, 0x6B/0x0B → 8, 0x03 → 0.

write_page_size: u32

Flash page size for program operations. Programs are split so they never cross a page boundary (the flash wraps within a page otherwise).

sample_delay: u8

RX sample delay, in SCK cycles.

Must be at least 1 for normal-speed transfers: with 0 the sampled RX data is unreliable (RDSR returns garbage, breaking WIP polling). The default is 1, matching Nordic’s Zephyr driver.

capacity: u32

Flash capacity in bytes, used for bounds checks. 0 disables them.

Trait Implementations

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.
