Enum stm32_hal2::sai::FifoThresh

#[repr(u8)]
pub enum FifoThresh {
    Empty,
    T1_4,
    T1_2,
    T3_4,
    T3_4B,
    Full,
}

FIFO threshold. Affects xCR2 reg, FTH field. Affects when SAI interrupts, and DMA transfers occur.

Variants

Empty

FIFO empty (transmitter and receiver modes)

T1_4

FIFO ≤ ¼ but not empty (transmitter mode), FIFO < ¼ but not empty (receiver mode)

T1_2

¼ < FIFO ≤ ½ (transmitter mode), ¼ ≤ FIFO < ½ (receiver mode)

T3_4

½ < FIFO ≤ ¾ (transmitter mode), ½ ≤ FIFO < ¾ (receiver mode)

T3_4B

¾ < FIFO but not full (transmitter mode), ¾ ≤ FIFO but not full (receiver mode)

Full

FIFO full (transmitter and receiver modes)
