Enum rp2040_pac::i2c0::ic_raw_intr_stat::TX_EMPTY_A

pub enum TX_EMPTY_A {
    INACTIVE = 0,
    ACTIVE = 1,
}

The behavior of the TX_EMPTY interrupt status differs based on the TX_EMPTY_CTRL selection in the IC_CON register. - When TX_EMPTY_CTRL = 0: This bit is set to 1 when the transmit buffer is at or below the threshold value set in the IC_TX_TL register. - When TX_EMPTY_CTRL = 1: This bit is set to 1 when the transmit buffer is at or below the threshold value set in the IC_TX_TL register and the transmission of the address/data from the internal shift register for the most recently popped command is completed. It is automatically cleared by hardware when the buffer level goes above the threshold. When IC_ENABLE[0] is set to 0, the TX FIFO is flushed and held in reset. There the TX FIFO looks like it has no data within it, so this bit is set to 1, provided there is activity in the master or slave state machines. When there is no longer any activity, then with ic_en=0, this bit is set to 0.

Reset value: 0x0.

Value on reset: 0

Variants

INACTIVE = 0

0: TX_EMPTY interrupt is inactive

ACTIVE = 1

1: TX_EMPTY interrupt is active

Trait Implementations

impl Clone for TX_EMPTY_A

fn clone(&self) -> TX_EMPTY_A

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TX_EMPTY_A

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

Formats the value using the given formatter.

impl From<TX_EMPTY_A> for bool

fn from(variant: TX_EMPTY_A) -> Self

Converts to this type from the input type.

impl PartialEq for TX_EMPTY_A

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