Enum rp2040_pac::i2c0::ic_data_cmd::CMD_A

pub enum CMD_A {
    WRITE = 0,
    READ = 1,
}

This bit controls whether a read or a write is performed. This bit does not control the direction when the DW_apb_i2con acts as a slave. It controls only the direction when it acts as a master.

When a command is entered in the TX FIFO, this bit distinguishes the write and read commands. In slave-receiver mode, this bit is a ‘don’t care’ because writes to this register are not required. In slave-transmitter mode, a ‘0’ indicates that the data in IC_DATA_CMD is to be transmitted.

When programming this bit, you should remember the following: attempting to perform a read operation after a General Call command has been sent results in a TX_ABRT interrupt (bit 6 of the IC_RAW_INTR_STAT register), unless bit 11 (SPECIAL) in the IC_TAR register has been cleared. If a ‘1’ is written to this bit after receiving a RD_REQ interrupt, then a TX_ABRT interrupt occurs.

Reset value: 0x0

Value on reset: 0

Trait Implementations

impl Clone for CMD_A

fn clone(&self) -> CMD_A

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CMD_A

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

Formats the value using the given formatter.

impl From<CMD_A> for bool

fn from(variant: CMD_A) -> Self

Converts to this type from the input type.

impl PartialEq for CMD_A

fn eq(&self, other: &CMD_A) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
